A standard four-drawer filing cabinet is 52 inches high and 15 inches wide. If it is evenly loaded, the center of gravity is at the center of the cabinet. A worker is tilting a filing cabinet to the side to clean under it. To what angle can he tilt the cabinet before it tips over?
To get up on the roof, a person (mass 87.0 kg) places a 5.60 m aluminum ladder (mass 14.0 kg) against the house on a concrete pad with the base of the ladder 2.00 m from the house. The ladder rests against a plastic rain gutter, which we can assume to be frictionless. The center of mass of the ladder is 2 m from the bottom. The person is standing 3 m from the bottom. What are the magnitudes (in N) of the forces on the ladder at the top and bottom?

A 2.0-m-long slab of concrete is supported by rollers, as shown. If the slab is pushed to the right, it will move off the supporting rollers, one by one, on the left side. How far can the slab be moved before its center of gravity is to the right of the contact point with the rightmost roller—at which point the slab begins to tip?

This can be done with the arrangement shown in the figure below. A woman of length 2.00 m lies on top of a horizontal plank so that her head is near the left end of the plank and her feet are near the right end. Each end of the plank is supported by a scale. The scale on the left is labeled Fg1, and reads a slightly larger value than the scale on the right, which is labeled Fg2. A light plank rests on two scales that read Fg1 = 380 N and Fg2 = 260 N. The scales are separated by a distance of 2.00 m. How far from the woman's feet is her center of gravity? ???? marrow_forward

- A gravity board is a convenient and quick way to determine the location of the center of gravity of a person. It consists of a horizontal board supported by a fulcrum at one end and a scale at the other end. To demonstrate this in class, your physics professor calls on you to lie horizontally on the board with the top of your head directly above the fulcrum point as shown in the figure. The fulcrum is 2.00 m from the scale. In preparation for this experiment, you had accurately weighed yourself and determined your mass to be 65.0 kg. When you are at rest on the gravity board, the scale advances 300 N beyond its reading when the board is there by itself. Use this data to determine the location of your center of gravity relative to the top of your head. -2 m еВookarrow_forwardStand with your heels and back against a wall and try to bend over and touch your toes. You’ll find that you have to stand away from the wall to do so without toppling over. Compare the minimum distance of your heels from the wall with that of a friend of the opposite sex. Who can touch their toes with their heels nearer to the wall males or females?
