A 40 kg sphere suspended by a thread of legnth 1 is oscillating in a vertial plane, the angular amplitude being theta_(0) . What is the tension in the thread when it makes an angle theta with the vertical during oscillations? If the thread can support a maximum tension of 80 kg-f, then what can be the maximum angular amplitude of oscillation of the sphere without breaking the rope?

A block placed on a rough inclined plane of inclination (=30^(@)) can just be pushed upwards by applying a force "F" as shown. If the angle of incrination of the inclined plane is increased to (theta 60^(@)), the same block can just be prevented from sliding down by application of a force of same magnitude. The coefficient of friction between the block and the inclined plane (sqrtn -1)/(sqrtn +1) where n is
