A demonstration gyroscope wheel is constructed by removingthe tire from a bicycle wheel 0.650 m in diameter, wrapping leadwire around the rim, and taping it in place. The shaft projects 0.200 mat each side of the wheel, and a woman holds the ends of the shaft inher hands. The mass of the system is 8.00 kg; its entire mass may be assumedto be located at its rim. The shaft is horizontal, and the wheel isspinning about the shaft at 5.00 rev/s. Find the magnitude and directionof the force each hand exerts on the shaft (a) when the shaft is at rest;(b) when the shaft is rotating in a horizontal plane about its center at0.050 rev/s; (c) when the shaft is rotating in a horizontal plane about itscenter at 0.300 rev/s. (d) At what rate must the shaft rotate in order thatit may be supported at one end only?
Q4: of a car غطاء محرك The i Jul. The bonnet is held open at an angle of 60° to the horizontal by a vertical force V applied at one end of the bonnet (shown on the diagram). The long, has a weight of 25 N and its center diagram shows the open bonnet bonnet is 0.90 m of gravity G is 0.35 m from the hinge at O. 1) On the diagram, draw and label the two forces other than V acting on the bonnet.

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=
