Question

A sign is supported by a cable and a horizontal beam.The beam has a length 1.4 m and a uniform mass of12 kg.a) If the cable is attached to the beam at a distance of 1.0 m from the hinge, what is the tension in the cable? (b) If the cable breaks, what is the net torque on the beam the instant thereafter?

Answer 1

Where is the sign? waht is its mass?

Answer 2

The sign has a mass of 95 kg and the cable makes 31 degrees with the beam

Answer 3

But the question is how is the sign attached to the beam. Where is the load on the beam?

Answer 4

Calculate the location and amount of force required to cause this system to be in equilibrium. Draw this force on the diagrm below showing direction, magnitude, and location. The rod weights 200 lb.
