K.C.S.E Physics Q & A - MODEL 2008PP1QN19
​ a) State the principle of moments.
b) A uniform metal strip is 3.0cm wide, 0.6cm thick d 100cm long. The density of the metal is 2.7 g/cm3. (i) Determine the weight of the strip. The strip placed n a pivot and kept in equilibrium by forces as shown in fig. 13 
​(ii) Determine the value of F and R
(iii) X is the distance from the end of the plank to the point of application of force F. Force F is now applied at various points nearer to the pivot so that x increases. Equilibrium is maintained all the time. On the axes provided sketch the relation between force F and x. 
​(iv) Give a reason for the answer in (iii) above

John carried a uniform post of mass 20kg horizontally on his shoulder as shown in fig 6. He placed the post on his shoulder such that the centre of gravity of the pole is 1.0m behind him. He balanced the post by applying a downward force F at a point 0.5m on the part of the post in front of him.
Determine the value of the force F.
