Does Shaft Length Affect Torque?

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)..

How is shaft length calculated?

Inputs that we need to calculate shaft diameterτ = Torsional stress induced at the outer surface of the shaft (Maximum Shear stress).r = Radius of the shaft.T = Twisting Moment or Torque.J = Polar moment of inertia.C = Modulus of rigidity for the shaft material.l = Length of the shaft.More items…•May 14, 2018

Does torque cause normal stress?

Normal stress and normal strain (which are caused by tension and compression) occur when a force is applied normal (perpendicular) to an area. Torque on a shaft causes shear stress. The torsion, or twist, induced when torque is applied to a shaft causes a distribution of stress over the shaft’s cross-sectional area.

How does shaft torque effect ball flight?

This is because in the downswing, a higher-torque shaft will cause the clubhead to twist open heading into impact. And because this shaft has a high torque, it won’t “snap back to square” as quickly as necessary, which is why higher-torque shafts tend to create a more rightward dispersion for a right-handed golfer.

How do you calculate shaft torque?

For motors, find torque (in ft-lb) using this equation: T = (HP*5252)/rpm.

What happens if golf shaft is too stiff?

If your golf shaft is too stiff and your swing speed is too slow, your well-struck shot will be limited on both carry distance and shot trajectory; a too-stiff golf shaft will most often lead to weak fades or slices.

Does a lighter shaft increase swing speed?

A lighter driver shaft rarely leads to a faster swing. “Only 12 percent of golfers swing their fastest with the lightest club,” Mucklow says.

What is the difference between torque and torsion?

Torsion happens when the torque causes a shear stress to be applied on the body. The main difference between torque and torsion is that torque describes something that is capable of producing an angular acceleration, whereas torsion describes the twist formed in a body due to a torque.

What is lost torque?

In a DC Motor, the complete electromagnetic torque (T) developed in the armature is not available on the shaft. … The difference between the armature torque and the shaft torque ( Ta – Tsh ) is known as the lost torque and is due to the formation of the torque.

How is motor torque calculated?

The required torque is calculated by multiplying the sum of load torque and acceleration torque by the safety factor. When the required torque for the motor varies over time, determine if the motor can be used by calculating the effective load torque.

How does torque affect driver shaft?

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). A golfer’s swing, and the clubhead attached to the end of the shaft, exert forces on the shaft that lead to twisting.

How do you calculate stress torque?

Torsion Formula We want to find the maximum shear stress τmax which occurs in a circular shaft of radius c due to the application of a torque T. Using the assumptions above, we have, at any point r inside the shaft, the shear stress is τr = r/c τmax.

How do we calculate 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 is torque transmitted?

Power transmission between two rotating components requires a secure connection between the shaft of the driving component, and the hub of the mating part. One way to ensure torque transmission without slipping is by using a keyed connection.

What is G in torsion formula?

G = modulus of rigidity (PanGlobal and Reed’s) or shear modulus (everybody else), [Pa, psi] θ = angle of twist, [rad] L = length of the shaft, [m, in]

What is torque in a shaft?

Torque is defined as “a twisting force that tends to cause rotation.” In the case of a golf shaft, it’s the amount of twisting (or lack thereof) that occurs during the swing. … The lower the torque number — it’s measured in degrees — the more resistant the shaft is to unwanted twisting.

What is Torque in strength of materials?

Torque is a moment that twists a structure. Unlike axial loads which produce a uniform, or average, stress over the cross section of the object, a torque creates a distribution of stress over the cross section.

How do you convert torque to power?

Torque ( = 63,025 x Power (HP) / Speed (RPM)Power (HP) = Torque ( x Speed (RPM) / 63,025.Torque (N.m) = 9.5488 x Power (kW) / Speed (RPM)Power (kW) = Torque (N.m) x Speed (RPM) / 9.5488.
