A solid cylinder of radius m is kept on an inclined plane on its base and it does not slide. The angle of incline plane is 53^(@) with horizontal and it is fixed. What will be maxcimum height (in meters) of the cylinder for it not to topple.

A solid cylinder of radius 0.35 m is released from rest from a height of 1.8 m and rolls down the incline as shown in the figure. What is the angular speed of the cylinder when it reaches the horizontal surface?

Water level is maintained ina cylindrical vessel up to a fixed height H. The vessel is kept on a horizontal plane. At what height above the bottom should a hole be made in the vessel so that the water stream coming out of the hole strikes the horizontal plane at the greatest distance from the vessel.

A right cylindrical vessel is full with water. How many right cones having the same diameter and height as that of the right cylinder will be needed to store that water ? (Take pi = (22)/(7) ).

A tank of height H and base area A is half filled with water and there is a small orifice at the bottom and there is a heavy solid cylinder having base area (A)/(3) and height of the cylinder is same as that of the tak. The water is flowing out of the orifice. Here cylinder is put into the tank to increase the speed of water flowing out. After long time, when the height of water inside the tank again becomes equal to (H)/(2) , the solid cylinder is taken out. then the velocity of liquid flowing out of the orifice (just after removing the cylinder) will be
