Ancient pyramid builders are balancinga uniform rectangular stoneslab of weight w, tipped at anangle u above the horizontal, usinga rope (Fig.). The rope isheld by five workers who share theforce equally. (a) If u = 20.0°, whatforce does each worker exert on therope? (b) As u increases, does eachworker have to exert more or lessforce than in part (a), assuming theydo not change the angle of the rope? Why? (c) At what angle do theworkers need to exert no force to balance the slab? What happens if uexceeds this value?

Consider a floor crane operated by a driver which carries a drum as shown in figure. The total weight of floor crane and driver is 2700 kg acting at the point of center of gravity, G. mm; = 1 = Considering L1 = 14m, L2= 3 m L3 - 6 m, 14 = 2 m LS = 1 m; L6=7m 1. If the weight of the drum lifted by the floor crane is 800 kg, determine the total normal reaction on the rear wheels at A and total normal reaction on the front wheels at B when the boom is inclined at an angle of 25" with the horizontal, 2. Utilizing the same data given above for the same position of boom, determine the largest weight of the drum that can be lifted without causing the crane to overturn. (Hint: When the floor crane tends to overturn about point B, the wheel at A will leave the ground). Note: 1. Consider the entire system as coplanar 2. Take g 9.81 m/s wherever necessary = 9 Total normal reaction on the rear wheels at A= Total normal reaction on the front wheels at B= Largest weight of the drum=
