... Q5.2. Reason: Objects in static equilibrium do not accelerate and remain at rest. Objects in dynamic equilibrium do not accelerate and move with constant velocity. (a) The girder is moving at constant speed. We assume it’s being lifted straight up. If so, it’s in dynamic equilibrium. (b) Since the g ...

... We will use a spring scale to measure the size of forces. First you need to calibrate the spring scale. Hold the scale horizontally or vertically just as you will use it when measuring, but without pulling on the hook. Adjust the scale (a sliding cover or nut at the top) so it reads zero. The scale ...
