Suppose you’re building a contraption which contains a solid rod of length L = 12.5 m and mass 4.9 kg. This rod has its lower end barely above the ground at an angle of 20.6 degrees with respect to the horizontal, and is ultimately held up by a rope connected at a distance L/4 from the top of the rod making an angle of 20.6 degrees with respect to the rod. The top of the rod may rotate as it is held in place by a bolt connected to a wall. Calculate the tension in the rope which keeps the rod from touching the ground.

I see a long string of what seem to be standard end of semester questions and I am being asked to do them despite having done so half a century ago. I see no attempt by the student or students to do the problems or any indication of what the difficulty is. All I see is an attempt to get me to just do the work for the student, which is not likely to impress the teacher much. Forget it. I do not need the practice.
This is the same person who posted that long dump of homework questions below, too.

Tension = (2*M*G*Cos*theta1) / (Sin*theta2)
