ABSTRACT
A force F newtons applied at right angles to a rod of length l metres pivoted at P (Figure 30) produces a turning moment M, where
M = F×l newtonmetres (Nm)
(Note This turning moment is produced whether or not the bar is actually free to turn.)
A horizontal bar 0.5m long is arranged as in Figure 30. Calculate the force required
in order to produce a moment of 250Nm.
