Q4

A rod is attached to a pivot on the wall at one end and suspended horizontally at the other end by a wire as shown in Figure. The wire makes 30° to the rod. The rod has mass M = 2.0 kg and length L-4.0 m. At the end suspended by the wire, an object of mass m - 1.0 kg is hung by a wire. Find the tensin T on the wire that suspends the rod in N. wire R 30° L rod pivot m

As shown in the figure, the member is anchored at A and section AB lies in the x–y plane. The dimensions are x1 = 1.6 m, y1 = 1.8 m, and z1 = 1.6 m. The force applied at point C is F=[−180 i+60 j+165 k] N. I need the answers in three components:  (I,j,k)N*M There are only two questions I hope anyone can help me to solve it, and show me how to do it. 1) Using the position vector from A to C, calculate the moment about segment AB due to force F. 2) Using the position vector from B to C, calculate the moment about segment AB due to force F. Thank you

Can you explain to me the encircled part of the solution on the second picture and what concept is used in order to come up with such solution. The first picture is the problem itself, the second picture is the solution

As the electric motor rotates at a constant speed, it applies a torque of 500 Nm to the ABCD shaft. Determine the torsion angle between B and C since G = 27 GPa and the torques shown in the figure are applied to the pulleys B and C.
