1) In using the pliers shown in Figure 1 below, 150 N forces are applied to each of the handles.
(i) Draw the free body diagrams of each element of the pliers clearly showing all the operating forces and moments ( diagram should be neatly drawn )

[ 8 marks ]
(ii) Write down the relevant equations of equilibrium with respect to a suitable axes system of your choice.
[ 8 marks ]
(iii) Determine the magnitude of the forces exerted on the bolt at E as a result of the forces applied on the handles.
[ 7 marks ]
(iv) Carry out further analysis to prove the validity of the results you have obtained in part (iii) above.
