1) A force of 730 N is applied to rotate the bar about the axis at A. The force application is 1.3m from the axis of rotation. What is the moment about the axis?   a) 7300 N b) 94.9 Nm c) 949 Nm d) 561 Nm e) 561 N 2) What is the resultant moment in the figure depicted?  a) 252.7 Nm clockwise b) 252.7 Nm anti clockwise c) 133.0 Nm clockwise d) 133.0 Nm anti clockwise 3) A symmetrical seesaw has 2 forces acting vertically downwards on it, yet is in a state of equilibrium. One force is 320 N, applied 1.6 metres from the axis of rotation. The second force is 410 N. How far from the centre of rotation is this force acting?  a) 1.6 m b) it is not possible to say c) -1.6 m d) 1.25 m
