If the load lifted is 45000N, find thetension in the wire and the compression force in the boom Neglect the weight of theboom.2. A square is acted upon by the forces of 4, 6, 8, and 12N respectively along the four sidesas shown. If the length of the side of the square is 0.5m, what is the resultant torqueacting to rotate the square about an axis through A?jON4N12N8N3.Two people carry a heavy electric motor by placing it on a light board 2.00 m in length.One person lifts at one end with a force of 700N, and the other lifts the opposite end witha force of 500N. What is the weight of the motor, and where along the board is its centerof gravity located? (Note: The center of gravity of an object is the point where theweight passes through.)4. A uniform ladder 10m long and weighing 350N rests against a smooth wall at an angleof 30° with the wall. A 700N man stand 6m up from the bottom of the ladder. Find thehorizontal force necessary at the base to keep the ladder from slipping.
