A cylindrical transmission shaft has a shear modulus of 80 GPa and operates at 500 rpm with an angle of twist of 0.5 degrees. The power transmitted by the shaft is ______ kW. (Rounded off to two decimal places)

238.64 kW

Fill in the blank: The maximum shear strain in a cylindrical rod twisted by an angle of 10º is represented as p x 10⁻³. The value of p is equal to ______.

0.8

True or False: In an Oldham coupling, bending load is transferred along the shaft axis.

False. Bending load is not transferred along the shaft axis; it is primarily a torsional connection.

What is the torsional stiffness of a hollow circular shaft with inner radius 10 mm, outer radius 20 mm, and length 1 m, if the shear modulus is 150 GPa? (in kN-m/rad)

35.34 kN-m/rad

Riddle: I can twist and turn, but my shape is always round; my strength is defined by my radius, and in torsion, I am renowned. What am I?

D) θs = θH and τs <>

Fill in the blank: The maximum torque transmitted by a circular solid shaft is derived from the maximum shear stress induced at the ______.

Outer surface

True or False: The polar moment of inertia for a solid circular section is greater than that for a hollow circular section of the same outer diameter.

True.

What is the relationship between torque and angle of twist for a shaft? Express it mathematically.

T = Kθ, where K is the torsional stiffness.

Riddle: I am defined as the energy stored when a shaft twists, and my value depends on torque and length. What am I?

Torsional strain energy
