Please make it clear what the answers are

The crane consists of three parts, which have weights of W1 = 37001b W2 = 7501b W3 = 13001b and centers of gravity at G1, G2 and G3. respectively. Neglecting the weight of the boom, determine (a) the reactions on each of the four tires if the load is hoisted at constant velocity and has a weight of 8401b . and (b). with the boom held in the position shown, the maximum load the crane can lift without tipping over. (Figure Determine the reactions on each of the front tires. Express your answers using three significant figures separated by a comma. Determine the reactions on each of the rear tires. Express your answer to three significant figures and include the appropriate units. Determine the maximum load the crane can lift without tipping over. Express your answer to three significant figures and include the appropriate units.

Explanation / Answer

Toatl load=w1+w2+w3=3700+750+1300=5750lb

taking moment about B

Let ra be the load on the front tires

and rb be the load on the rear tires.

14*w1+6*w2-1*w3-ra*15=0

Part A) ra=3666.66lb

Part B)

ra+rb=total load=5750lb

rb=2083.34lb

Part C

In order the truck must not topple while lifting maximum load W.

Taking moment about A ( since the truck will pivot about A while toppling)

W*10=3*w1+11*w2+18*w2

=3*3700+11*750+18*1300

W=4275lb
