= 800 N at If the man-lift consists of 3 parts with weights of G1 = 2500 N, G2 = 1000 N, G3 the centres of mass at G1, G2 and G3 respectively. With the boom held as shown, determine the maximum weight of the man that can be lifted without tipping over.

The center of gravity of the nonhomogeneous bar AB is located at G. Find the angle at which the bar will be in equilibrium if it is free to slide on the frictionless cylindrical surface.

The homogeneous plate of weight W is supported by a ball-and-socket joint at D and three wires. Draw the FBD of the plate and count the unknowns.

Determine the smallest horizontal force P that would push the homogeneous cylinder of weight W over the curb. Neglect friction.

I got -133.344Kn but that was incorrect. Need help and the answer has to be to three decimal points.

A 200 lb rock is being lifted by a pry bar. Determine the force “P” required to lift the rock into the position show.

the tree feller cuts off large trees near ground level and then continues to grasp the trunk. Determine the force in hydraulic cylinder AB for the position shown if the tree weighs 6000lb. Determine the required pressure on the 4.72-in.-diameter piston of the cylinder. draw the free body diagram

2250 2040 1080 COOPER FEETF 10-1 Dimensions in millimeters The three feller cuts off large trees near ground level and then continues to grasp the trunk. Determine the force in hydrolic AB for the position shown if the tree has a mass of 3 Mg. Determine the required pressure on the 120 mm diameter piston of cylinder.

Please write solution to be legible and clear. Thanks

According to the answer key-  1. 32.4 lb 2. Fs = 38.1 lb 3. Fk = 32.4 lb 4. No 5. Yes – box is sliding up the incline (to the right)
