A uniform beam of length 5.4 m and mass 12 kg supports a28 kg mass. The cable is at an angle of 58.4 with the wall and the beam is attached to the wall by pivoting pin at an angle of 58.8 by the wall.
Discover the tension in the cable. The acceleration of gravity is9.8. Answer in units of N.
What is the magnitude of the force that the wall applies to the beam at the beam? Answer in units of N.
