MECHANICS.

Examiner-REV. T. J. POTTER, M.A.

1. Define the moment of a force with respect to a point. State the condition of equilibrium of pressures acting on a lever.

2. A rower pushes with his feet against the stretcher with a force equal to that with which he pulls the oar; explain how the boat is propelled.

3. Describe the Wheel and Axle, and some of its modifications.

4. Explain how a person can pull himself upwards by means of a rope passing over a single fixed pulley. What force must he exert to do this?

5. Define the centre of gravity of a body, and of a system of bodies. The distance of the moon from the earth is 240,000 miles; how far from the centre of the earth is the centre of gravity of the two bodies, the mass of the earth being 88 times that of the moon?

6. How is the work done by a machine in raising weights measured? Find the amount of labour expended by a man, whose weight is 150 lbs., in walking 10 miles, if he raises his centre of gravity 2 inches at each step, the average length of a step being 2 ft. 6 inches.

7. "Action and Reaction are equal and opposite." Give illustrations of this law.

8. Why does a pendulum swing to the same distance on both sides of the lowest point?

Explain, by means of this, the motion of the leg in walking.
