2) A drawbridge has mass M and length L and is approximately uniform. It has a hinge at the right end, and is being pulled up via a cable (F7) that is pointed 45° up from "to the right" and is connected at L/3 from the left end. Assume that the tension is just enough that there's no normal force at the left end of the bridge. Draw a torque diagram (as taught in this course) for the bridge, with the hinge as the pivot point. Assume it is stationary and not accelerating.

Cables

Cables are collections of wires, alternatively referred to as a cord, connector, or plug. They are one or more wires covered in a plastic covering that allows for the transmission of power or data between devices. The earliest use of recognizable electrical cable was the early commercialized telegraph lines. These were iron-made and tedious to produce and install cabling.

Question

2) A drawbridge has mass M and length L and is approximately uniform. It has a hinge
at the right end, and is being pulled up via a cable (F7) that is pointed 45° up from “to
the right" and is connected at L/3 from the left end. Assume that the tension is just
enough that there's no normal force at the left end of the bridge. Draw a torque diagram
(as taught in this course) for the bridge, with the hinge as the pivot point. Assume it is
stationary and not accelerating.
