0 1י APPLIED SCIENCES IV iJr05tat1ciS anil OiMMiiurtf Determine the conditions of equilibrium of floating body When the floating body has fixed point round which it may freely turn what is the condition of equilibrium and what is the pressure on the fixed point Find the centre of pressure of square immersed vertically in fluid one side being parallel to and at given depth beneath the surface of the fluid Show that the barometer may be used to determine the height of mountain Explain the nature of the chief corrections to be made in the barometrical measurement of heights Determine the relation between the pressure density and temperature of an elastic fluid Determine the velocity of fluid issuing from small orifice under given pressure State the principle of work show that the principle of virtual velocities is particular case of it and prove that the work done by set of forces is the same as the work done by their resultant AC and are four equal uniform rods at right angles each weighing 10 lbs ami feet long Β CD and Ε Β are also four equal uniform rods each weighing ι
