Concept explainers

Center of Gravity and Centroid

The term center of gravity indicates the position or location of a point about which the whole weight of a body or system is supposed to be concentrated, which means the whole weight of the body or system works through this point. It is closely related to mass distribution. For all positions of the body, the center of gravity would be a single point.

In winter season, he chemical observed a snow from a pavement that is being scooped up to a height of 40 ft by an endless bucket-scoop. and is then dropped into a container. He noticed that, at the highest point, the snow moves at 3 k’s. A total of 66 hp is needed to scoop snow at the rate of 100 lb’’s. Assuming a loss of 10% due to friction, calculate the percentage of tool work need to melt and break up the snow.

In a manufacturing process, a drill press automatically drills a hole into a sheet metal part on a conveyor. In the drilling operation the drill bit starts at rest direcdly above the part, descends quickly, drills a hole, and quickly returns to the start position. The maximum vertical speed of the drill bit is 4 in./s, and while drilling the hole, it must move no more than 2.6 in./s to avoid warping the metal. Let s(t) be the drill biť's height (in inches) above the part as a function of time t in seconds. Sketch possible graphs of the drill bit's velocity [s'(t)] and acceleration [s"(t)].
