Given. m = 20.0 kg ; M1 = 54.0 kg ; M2 = 37.0 kg ; L1 = 2.90 m ; L2 = 5.40 m ; and θ = 43.0°. a) How many forces are acting on the beam (treat the interaction at the pivot with the wall as 2 forces)? RIGHT! b) What is in N the tension of the cable? c) What is in N, H, the horizontal component of the force exerted by the wall onto the beam? Assume the positive direction points towards the right. d) What is in N, V, the vertical component of the force exerted by the wall onto the beam? Assume the positive direction points upwards. Use 10.0 N/kg for g. 2. I believe to find tension I am using Ft=Fg x m x g but maybe I am using the wrong values? 3. I am honestly confused. I counted the forces and got that correct. I am unsure how to solve the other parts??
