Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

Determine the force exerted at B by the hydraulic cylinder BD when theta = 35 degrees.
Q.3) A luggage transport truck is used to raise and lower luggage from an aircraft. A piece of luggage weighing 450 lbs. is supported in the position shown with a center of gravity at point G. The raising and lowering mechanism are connected to the truck bed by a pin support at F and a roller support at H, and to the luggage platform by a pin support at C and a roller support at D. The hydraulic strut AB is pinned at either end and used to raise and lower the mechanism. Assume the weight of all members within the mechanism are negligible, that point C is vertically aligned with F, point D is vertically aligned with H, and that the strut AB is vertically 20maint oriented.

In order to unscrew the tapped faucet A , a plumber uses two pipe wrenches as shown. By exerting a 40-lb force on each wrench at a distance of 10 in. from the axis of the pipe and in a direction perpendicular to the pipe and to the wrench, he prevents the pipe from rotating, and thus he avoids loosening or further tightening the joint between the pipe and the tapped elbow C . Determine (a) the angle 0 that the wrench at A should form with the vertical if elbow C is not to rotate about the vertical, (b) the force-couple system at C equivalent to the two 40-lb forces when this condition is satisfied.
