The angle between the beam and the horizontal is 66 degrees and the angle between supporting cable and the horizontal is 39 degrees. Part a: what are the angles between the cable supporting the load and the beam and between the cable supporting the beam and the beam? Part b: what are the 2 equations gotten by newton’s 2nd law (using f for horizontal component force at the surface and N for the vertical component force at the surface)? Part c: what is the torque equation (using L for the length of beam)? Part d: if the mass of the beam is 200kg and the mass of the load is 1000kg, what are all forces on the beam?

A block of mass 3 kg is hung from a spring,

A block of mass 3 kg is hung from a spring, causing it to stretch 18 cm at equilibrium, as shown below. The 3 kg block is then replaced by a 4 kg block, and the new block is released from the position shown below, at which point the spring is unstretched. How far will the 4 kg block fall before its direction is reversed? Hint: For the new block case, the total distance of fall is twice the amplitude of the oscillation. The acceleration of gravity is 9.8 m/s2. Answer in units of cm
