What is the primary function of a shaft in mechanical systems?

To transmit power.

Fill in the blank: The two primary methods for shaft design are based on Strength and ______.

Stiffness

True or False: An axle is a rotating member that transmits torque.

False. An axle is a non-rotating member that supports rotating wheels and does not transmit torque.

Which material is commonly used for general purpose transmission shafts due to its smooth finish? A) Hot-rolled plain carbon steel B) Alloy steels C) Cold-drawn plain carbon/alloy composition D) Stainless steel

C) Cold-drawn plain carbon/alloy composition

Riddle: I am used to transmit torque but do not rotate, and I support the wheels. What am I?

Axle

What is the ASME allowable design stress for steel shafts without keyways?

55 MPa

Fill in the blank: The bending stress equation is given by the formula M/d₀, where M is the ______.

Bending moment

True or False: The maximum shear stress theory states that a machine member fails when the average shear stress exceeds the material's shear strength.

False. It states that failure occurs when the maximum shear stress exceeds the maximum allowable shear stress.

What are the typical size increments for solid shafts from 25 mm to 50 mm?

1.0 mm increments

In shaft design, what factor is used to account for buckling under axial loads?

Column action factor (α)

Fill in the blank: The maximum deflection of a shaft is required to be within a prescribed limit, typically expressed in ______.

Millimeters

Which criterion is most commonly used in design for variable loads in shafts?

Soderberg criterion
