DL: Activity 1.7: It is Universal

What is a universal joint?

• A joint that allows for the transmission of electrical current between two wires.

• A joint that connects two bones in the human body.

• A type of joint used in plumbing systems.

• A mechanical joint that allows for the transmission of rotary motion between two shafts that are not in a straight line.

What are the two main purposes of a universal joint?
