What is torque on a shaft?

"Torque" is a property of golf shafts that describes how much the shaft is prone to twisting during the golf swing. A shaft with a lower torque rating means the shaft better resists twisting; a shaft with a higher torque rating means the shaft is more prone to twisting (all other things being equal).

.

Subsequently, one may also ask, how do you measure torque on a shaft?

Theoretically, we can use the following formulas,

  1. Torque= Force*perpendicular distance (from the center axis to the point of action of force)
  2. Power=(2*pi*N*T)/60.

Subsequently, question is, is torque constant along a shaft? Torque -- also called MOMENT OF A FORCE, in physics, the tendency of a force to rotate the body to which it is applied. a) Torque stays constant along a shaft (so we're neglecting any friction in bearings that hold the shaft in place).

Also to know is, what does torque and kick point mean in a golf shaft?

In golf, torque measures a shaft's resistance to twisting. Some very fast swings (120 miles per hour or higher) may need very low torque shafts. Now for kick point. If you were able to push on both ends of a shaft at the same time with quite a bit of force, it would bend under the load.

What is considered low torque golf shaft?

A low torque shaft means that the shaft actually has a high degree of resistance to twisting. The “low” refers to the number assigned to the torque value. For example, a shaft that has a torque value of 2.5* has a very low degree of torque, which means that is has a high ability to resist twisting.

Related Question Answers

How do you determine torque?

A practical way to calculate the magnitude of the torque is to first determine the lever arm and then multiply it times the applied force. The lever arm is the perpendicular distance from the axis of rotation to the line of action of the force. and the magnitude of the torque is τ = N m.

How do you find maximum torque?

Torque on the loop can be found using τ=NIABsinθ τ = N I A B sin ? . Maximum torque occurs when θ = 90º and sin θ = 1.

How much torque can a shaft handle?

Theoretically, this shaft is capable of transmitting 1,700 hp, so it is more than sufficient for the 200 hp requirement. The amount of torque that a hollow shaft can transmit depends on thickness of the wall between its inside and outside diameters. A thinner wall cannot handle as much torque as a thicker one.

What is J in torque equation?

General torsion equation J = polar moment of inertia or polar second moment of area about shaft axis, [m4, in4] τ = shear stress at outer fibre, [Pa, psi] r = radius of the shaft, [m, in] G = modulus of rigidity (PanGlobal and Reed's) or shear modulus (everybody else), [Pa, psi] θ = angle of twist, [rad]

What is Torque example?

Mathematically, torque is described by this equation: torque equals force times perpendicular distance. For example, if you're pushing on a door, then the distance to the hinge is the perpendicular distance -- the line to the hinge is at 90 degrees to the force arrow (the direction you're pushing).

What does torque mean?

Torque is the amount of “turning power” you have, in the same way that you turn a wrench. 369 foot-pounds means that if you had a wrench that was 1 foot long, and applied a force of 369 pounds directly perpendicular to that wrench, you would get 369 foot-pounds of torque. (This is known as machine torque.)

What is polar moment of inertia of shaft?

Simply put, the polar moment of inertia is a shaft or beam's resistance to being distorted by torsion, as a function of its shape. The rigidity comes from the object's cross-sectional area only, and does not depend on its material composition or shear modulus.

Does higher torque golf shaft mean?

"Torque" is a property of golf shafts that describes how much the shaft is prone to twisting during the golf swing. A shaft with a lower torque rating means the shaft better resists twisting; a shaft with a higher torque rating means the shaft is more prone to twisting (all other things being equal).

What is Torque in golf swing?

Torque, which equates to Force x Distance, is the turning force that changes an object's rate of rotation. In a golfing context, this usually refers to the rotation of the shoulders during the backswing, and the hips during the swing itself.

Does a lighter shaft increase swing speed?

In theory, lighter shafts allow golfers to swing faster with the same effort, and a faster-moving club head means more distance.

Does shaft flex matter?

Shafts can have the same flex but different weight, bend profile, or torque. Also, the player's tempo has a big impact on how they load the shaft. A player with a slower swing and aggressive tempo may bend the shaft just as much as a player with a faster swing and slower tempo.

What gram shaft should I use?

The lighter the shaft, the faster the club can be swung. The faster the club is moving, the farther the ball goes. It is why the most popular weight for driver shaft-weights on the PGA Tour is still in the mid-60-gram range, with some players having tried shafts less than 50 grams.

What is the effect of torque on a golf shaft?

The toe gets "left behind" as you start your downswing, then it "catches up" and returns to its normal position at impact. The shaft resists that twisting motion, allowing only a certain amount. The twisting that is allowed, measured in degrees, is the shaft's torque.

How far should you hit a 7 iron?

For example, you might think that you are hitting your 7-iron 155 yards. You'll typically pull that club on the course from that distance, but in reality you might be hitting it 145 yards.

How far does Tiger Woods hit a 7 iron?

Tiger Woods distance varies from club to club. According to Golf Digest, Tiger hits the driver an average of 285 yards with carry. His long irons (2- to 4-iron) range from 250 to 200 yards. His middle irons (5, 6, 7) range from 208 to 172 yards.

Is driver shaft too stiff?

If your club shafts are too stiff, you'll have trouble loading them properly during your downswing. When the clubhead gets to the ball, the shaft won't unload properly and the face will remain slightly open, causing a slice.

What is the torque of a motor?

Torque is the turning force through a radius - with the units Nm in the SI-system and the units lb ft in the imperial system. The torque developed by an asynchronous induction motor varies when the motor accelerates from zero to maximum operating speed.

What does negative torque mean?

Oh, torque can be positive or negative. Let us say that a positive torque would make a stationary object rotate counter clockwise and a negative torque would make it rotate clockwise. If you switched these, it wouldn't really matter too much. Also, the torque does depend on the point about which it is calculated.

Do two gears on the same shaft have the same torque?

Yes, they will rotate at the same speed and are called compound gears. The gears that make up a compound gear usually differ in size and have a different number of teeth. This is useful if there is a need to speed up or slow down the final output.
