A pair of tweezers is hinged at one end. The fingers squeeze the arms halfway along their length, and the object is gripped at the tip. If the fingers squeeze with 8 lb of force, the gripping force at the tip is about:
Correct answer: D - 4 lb
Rather than lifting a 500 lb crate straight up onto a loading dock, a worker slides it up a ramp to the same height. Ignoring friction, using the ramp:
Correct answer: B - Reduces the force needed but not the total work done
Two workers carry a 240 lb crate slung from a pole that rests on a shoulder of each. The crate hangs 3 ft from the front worker and 5 ft from the rear worker. The front worker is carrying about:
Correct answer: C - 150 lb
A uniform plank 12 ft long rests on a pivot placed 4 ft from its left end. A 90 lb weight is set on the extreme left end. Ignoring the weight of the plank itself, the weight that must be placed on the extreme right end to balance it is:
Correct answer: A - 45 lb
A block and tackle has one fixed block above and one movable block below. Four separate lengths of rope run between the two blocks and support the movable block, and a fifth length runs from the fixed block down to the worker's hands. Ignoring friction and the weight of the rope, the effort needed to hold a 600 lb load steady is about:
Correct answer: B - 150 lb
A drive pulley 9 inches in diameter is connected to a driven pulley 3 inches in diameter by a single belt that is crossed in a figure eight between them. The drive pulley turns clockwise at 240 rpm. Assuming no slip, the driven pulley turns at:
Correct answer: D - 720 rpm, counterclockwise
A 12-tooth driver gear meshes with a 36-tooth idler gear, which in turn meshes with a 24-tooth output gear. For each complete turn of the driver, the output gear makes:
Correct answer: A - 0.5 turn, in the same direction as the driver
A 15-tooth gear on a motor shaft drives a 60-tooth gear on an output shaft. Ignoring friction, the output shaft turns:
Correct answer: C - One quarter as fast, with four times the torque
A rectangular steel block is dragged at a steady speed across a concrete floor. The block is then stood on a narrower face, halving the area touching the floor, and dragged again at the same steady speed. The force needed to keep it moving is:
Correct answer: B - Roughly the same as before
From the same height above level ground, one steel ball is dropped straight down while an identical ball is fired horizontally from a spring launcher at the same instant. Ignoring air resistance, which ball reaches the ground first?
Correct answer: D - They reach the ground at the same instant
