One end of a uniform rod of weight w = 72.5 N and length L = 2.80 m is supported by a cable at an angle of theta = 33.5 degree above the rod. The other end rests on a small frictionless support and presses into a wall as shown in the figure. Determine the magnitude n of the vertical normal force exerted by the support on the rod and find the magnitude f of the tension in the cable....
A rod uniform and homogeneous AB of length L=4.00 m is attached to a wall as shown and secured via a massless rope BC of length l=5.00 ml=5.00 m to the wall (see Fig. 4). A mass M1=40.0 kg is attached to the rod at B. The rod itself has a mass M=2.00 kg. Assume that the tension in the string is T. Hint - set up the two force equations (along x and y axes) and the torque equation....

2. (50 points) A uniform rod of length L and mass m is hinged to a wall at one end and suspended from the wall by a cable that is attached to the other end of the rod at an angle of B to the rod (see figure below). Assume the cable has zero mass. There is a contact force at the pivot on the rod. The magnitude and direction of this force is unknown. In this problem you will...
Question 1: Hanging block (12 points) A horizontal rod of mass M and length L is attached to a hinge and supported at its end by a massless wire oriented at an angle o relative to the rod.

A uniform horizontal beam of length 8 m and weight 200 N is attached to a wall by a pin connection that allows the beam to rotate. Its far end is supported by a cable that makes an angle of 53degree with the horizontal. If a cable is strong enough to withstand T= 1200 N how heavy person can walk to the end of the beam? When that person was at the 0.75 distance from the wall, find: a. the...
A uniform horizontal beam with a length l = 8.00 m and weight of Wb = 200 N is attached to a wall by a pin connection.
