Question 13

A _____ consists of two individual U-joints connected by a centering socket yoke and a center yoke that functions like a ball and socket.

Accepted Answer

A double Cardan Universal joint, also known as a constant velocity joint (CV joint), consists of two individual U-joints connected by a centering socket yoke and a center yoke that functions like a ball and socket. It is commonly used in drive shafts to allow for flexibility and rotation while maintaining a constant velocity.

Question 14

_____ occur when opposing operating angles of two Universal joints cancel the oscillations developed by the individual Universal joint.

Accepted Answer

Canceling angles occur when the opposing operating angles of two Universal joints are set up in such a way that they cancel out the oscillations or vibrations developed by each individual Universal joint, leading to a smoother operation.

Question 17

Technician A says the Universal joint has a center cross with machined arms. Technician B says it has bearing cups that contain a set of ball bearings. Who is correct?

Accepted Answer

Technician A is correct because a universal joint typically has a center cross with machined arms, which is a key component of its design. Technician B is incorrect because universal joints do not use ball bearings in their bearing cups; instead, they use needle bearings.

Question 18

The Spicer style, mechanic's style (aka Detroit/Saginaw style), and the Cleveland style are  styles of _____.

Accepted Answer

The Spicer style, mechanic's style, and Cleveland style are all styles of single universal joints. Double universal joints and CV joints have different styles and designs. Drive shafts can use any of these styles of universal joints.
