Which type of coupling is designed to absorb some amount of misalignment between shafts?

Flexible couplings

Fill in the blank: A sleeve coupling consists of a cylindrical sleeve that is ______ to the shafts to be connected.

Keyed

True or False: Rigid couplings can accommodate significant misalignment between the shafts.

False. Rigid couplings cannot absorb any misalignment.

What is the primary purpose of keys in mechanical assemblies?

To secure machine parts and transmit torque

Riddle: I join two shafts, ensuring they align, but if they're not straight, I can't do my job fine. What am I?

Rigid coupling

What type of fastener is primarily used to prevent sliding between machine parts?

Pins

Fill in the blank: The shear stress in a rectangular sunk key is given by the formula ______.

Τ = T/(D * b)

Which coupling uses two flanges and bolts to transmit torque?

Flange coupling

True or False: The Oldham coupling is effective for accommodating angular misalignment.

True.

What is the typical diameter ratio for a clamp coupling in relation to shaft diameter?

Outside diameter d₀ is between 2 to 4 times the shaft diameter d.

Riddle: I’m a type of coupling that’s flexible and light, absorbing misalignment without much fight. What am I?

Flexible rubber-bushed coupling

What is the purpose of using taper pins instead of straight pins in mechanical assemblies?

Taper pins can be driven easily and allow for easier reaming of holes.
