Starting from rest, the elevator ascends, attaining its maximum speed of 1. It travels with this constant speed for the next The elevator then undergoes a uniform acceleration in the negative y direction for 1. What does the scale register: a before the elevator starts to move? As the lift is going up shouldn't the weight be more than what it was initially? Questions » Accounting » Auditing » A Questions Courses. Starting from rest, the The elevator then undergo A Jun 14 AM. Subhash P answered on June 16,

We shall use SAE 30 oil as a lubricant, at an inlet temperature of 45 oC.

A woman weighing 75 kg stands on a spring scale in elevator. During the first 3 seconds of motion from rest, the tension T in the hoisting cable is N. The total mass of the elevator , woman scale is kg. The elevator is moving in the upward direction means it is accelerating in the upward direction then.

These serve also to illustrate some further subtleties of physics and to help build problem-solving skills. Suppose two tugboats push on a barge at different angles, as shown in Figure 4. The first tugboat exerts a force of 2. If the mass of the barge is 5. Note: drag force is a frictional force exerted by fluids, such as air or water. The drag force opposes the motion of the object. The directions and magnitudes of acceleration and the applied forces are given in Figure 4. The system of interest here is the barge, since the forces on it are given as well as its acceleration. First, the resultant magnitude is given by the Pythagorean theorem:.

It is actually the normal force the scale has to exert to support your weight. When you and the scale are stationary with respect to each other, these forces balance out and your weight equals the normal force. What if you and your scale are in motion, like in an elevator? If the elevator is stopped, the scale reads what you would expect it to read, which is your weight in an elevator. The same is true when the elevator is moving at a constant velocity. There elevator is in equilibrium. You may notice that when the elevator begins to move, your weight seems to change. As the elevator begins to rise, you feel heavier.
