... length. From the point of view of static analysis the two 'structures' of Figure 23 are in principle no different. If we know that the forces F,and F, are both 10 N how can we find the weight, and the mass, of the load? This problem is different from those we looked at in Section 2.1 in that the for ...

... 1. Set up a simple pendulum. Pull the string aside so that it makes an angle of 30◦ with the vertical. This is called the initial angle. Let the object swing and record the time for ten full oscillations. Record the length of the string. This is the distance from the point where the string is attach ...

In the same manner, total work done by external forces is not, in general, equal to the work done by the total external force on the centre of mass. The latter equals the change in the kinetic energy of the centre of mass. There is an ...
