TIME: THREE HOURS.

N. B.-Answer only ten questions.

1. Enunciate and prove the proposition called the Polygon of Velocities.

2. A stone is thrown vertically upwards with a velocity of 90 feet per second.

3. When is force said to do work on a body? How is the work done measured ? Define the foot-pound, and find the work done by a man who lifts 120 lbs. through a height of 20 yards.

4. Two masses, m and M, are acted upon for the same time, by forces of 20 and 25 units respectively, and the same velocities are produced. Find m if M is 10 lbs.

5. Find the resultant of two forces acting on a particle, whose magnitudes are 10 and 12 respectively and whose directions are inclined at an angle of 60°.

6. A shell, initially at rest, bursts into two fragments whose masses are 12 and 20 pounds. The first moves off with a velocity of 25 ft. per second. Find the velocity of the second.

7. Shew that if three forces acting on a particle are in equilibrium, and if their directions are represented by the sides of a triangle taken in order, their magnitudes also are represented by those sides respectively.

8. Find the centre of Inertia (or of gravity) of a uniform, thin triangular plate.

9. Shew that the algebraic sum of the moments of two parallel forces about any point in their plane is equal to the moment of their resultant about the same point.

10. Describe the common Balance ; and show that the mass of a body may be determined by means of it.

11. The height of a smooth inclined plane is 3 ft. and its length 5 ft. Find what force acting up the plane will keep a body of 20 lbs. mass, in equilibrium on it.

12. Shew that the pressures, at all points in a horizontal plane, of a heavy fluid, are the same.

13. The pressure on the surface of a lake is equal to the weight of 14.5 lbs. per square inch. Find the pressure at a point 20 ft. below the surface. Find also the pressure on a horizontal surface of 2 sq. ft. area at that depth. (A cubic foot of water weighs 1000 oz.)

Mirabar, quid esset, quod tu mihi litteras mittere intermisisses : indicavit mihi Pansa meus Epicureum te esse factum. O castra praeclara ! quid tu fecisses, si te Tarentum et non Samarobrivam misissem? jam tum mihi non placebas, cum idem tuebare, quod Zeius familiaris meus. Sed quonam modo jus civile defendes, cum omnia tua causa facias, non civium? Ubi porro illa erit formula fiduciae UT INTER BONOS BENE AGIER OPORTET? Quis enim est, qui facit nihil nisi sua causa ? Quod jus statues COMMUNI DIVIDUNDO, cum commune nihil possit esse apud eos, qui omnia voluptate sua metiuntur ? Quo modo autem tibi placebit JOVEM LAPIDEM jrare, cum scias Jovem iratum esse nemini posse ?

Quid fiet porro poupulo Ulubrano, si tu statueris, TOALTEVEĞbai non oportere ? Qua re si plane a nobis deficis, moleste fero ; sin Pansae adsentari commodum est, ignosco. Modo scribe aliquando ad nos, quid agas et a nobis quid fieri aut curari velis.
