Question
A horizontal uniform beam AB of length 4 m and a mass of 20 kg is supported at the end B by means of a string which passes over a fixed, smooth pulley supporting a counterbalancing weight of 8 kg on the other side. What force, F, when applied at the point 
in a suitable direction, will hold the beam in static equilibrium ?
- F=160 N
- no force F, as specified, can hold the beam in static block
The correct answer is:
