UCE PHYSICS 2009 PAPER 2 QTN 2

(a) Define a moment of force.

(b) describe an experiment to determine the mass of a uniform meter rule using the principle of moments.

(c )

Figure 1 shows a uniform pole AB of length 2m and weight 50N supported at the ends A and B. A load of weight 500 N is suspended at a point 50cm from A.

Calculate the reaction forces R1 and R2 at the supports.

(d)(i) Explain what is meant by unstable equilibrium.

(ii) State two ways of increasing the stability of a body
