Chapter 8, Problem 39P
To determine

The force that the cable exerts at 37° to the horizontal oriented beam of mass 2kg and length 1.5m attached to the wall on the left, when a 2 kg pot is hanged 0.1 m away from the right end of the beam such that the cable is horizontally attached to the right end, and is connected to the point above the hinge on the wall. Also, the force that the wall hinge exerts on the beam (x and y components and the magnitude and direction of that force).

Can you help me solve this 2 question and teach me what we use to solve this
You are working during the summer at a company that builds theme parks. The company is designing an electromagnetic propulsion system for a new roller coaster. A model of a substructure of the device appears in the figure below. Two parallel, horizontal rails extend from left to right, with one rail behind the other. A cylindrical rod rests on top of and perpendicular to the rails at their left ends. The distance between the rails is d and the length of the rails is L. The magnetic field vector B points vertically down, perpendicular to the rails. Within the rod, the current I flows out of the page, from the rail in the back toward the rail in the front. The rod is of length d = 1.00 m and mass m = 0.700 kg. The rod carries a current I = 100 A in the direction shown and rolls along the rails of length L = 20.0 m without slipping. The entire system of rod and rails is immersed in a uniform downward-directed magnetic field with magnitude B = 2.30 T. The electromagnetic force on the rod…
Based on the graph, explain how centripetal force is affected when the hanging mass changes. Does your graph verify the relationship in the equation r = x^i + y^j = r cos ωt I + r sin ωt^j?
