A uniform rod of length `1m` having mass `1 kg` rests against a smooth wall at an angle of `30^(@)` with the ground. Calculate the force exerted by the ground on the rod. Take `g = 10 ms^(-2)`.

Figure shwos a uniform rod of length 30 cm having a mass of 3.0 kg. The strings shownin the figure are pulled by constant forces of 20 N and 32N. Find the force exerted by the 20 cm part of the rod on the 10 cm part. All the surfaces are smoth and the strings and the pulleys are light.
