In Fig. 5-25a, a passenger of mass m = 72.2 kg stands on a platform scale in an elevator cab. We are concerned with the scale readings when the cab is stationary and when it is moving up or down.
(a) Find a general solution for the scale readihng, whatever the vertical motion of the cab.

To find the general solution for the scale reading when a passenger of mass \( m = 72.2 \, \text{kg} \) stands on a platform scale in an elevator cab, we will analyze the forces acting on the passenger in different scenarios: when the elevator is stationary, moving upwards, and moving downwards. ### Step-by-Step Solution: 1. **Identify the Forces Acting on the Passenger:** - The weight of the passenger acting downwards: \( F_g = mg \) - The normal force exerted by the scale acting upwards: \( N \) ...

Pseudo force is an imaginary force which is recognised only by a non-inertial observer to explain the physical situation according to newton’s laws. Magnitude of pseudo force Fp is equal to the product of the mass m of the object and the acceleration a of the frame of reference. The direction of the force is opposite to the direction of acceleration, F_(p)=-ma spring weighing machine inside a stationary lift reads 50 kg when a man stand on it. What would happen to the scale reading if the lift is moving upward with (i) constant velocity (ii) constant acceleratioin

Many tall building have mass dampers, which are antisway devices to prevent them from oscillating in a wind. The device might be a block oscillating at the end of a spring and on a lubricated track. If the building sways, say eastward, the block also moves eastward but delayed enough so that when it finally moves, the building is then moving back westward. Thus, the motion of the oscillator is out of step with the motion of the building. Suppose the block has mass m= 2.72 xx 10^(5)kg and is designed to oscillate at frequency f= 10.0 Hz and with amplitude x_(m) = 20.0cm . What is the total mechanical energy E of the spring block system?
