Determine the force exerted on the cable by the man- Civil Engineering
1.The beam shown has a mass of 120 kg. Determine the reactions at pinned support A and smooth surface B.
2. The lever ABC is loaded and supported. Determine the force exerted on the lever by link CD, and determine the reactions at pinned support A.
3. The man has a mass of 75 kg, and the beam has a mass of 40 kg. The beam is in equilibrium with the man standing at the end and pulling on the cable. Determine the force exerted on the cable by the man and the reactions at pinned support C.
4. A frame is supported and loaded. Determine the reactions at pinned support A and rollersupport E. (Hint: Use a FBD of the frame as one whole body.)
