A solid wooden cylinder consists of a mass of 12 kg and a radius of 25 cm. It is suspended from its cylindrical axis by using a steel piano wire. It is viewed that a tangential force of around 1.5N is needed to ‘twist’ the mass via a 20 degree angle. From its position, the mass is released and let to rotate.
i) Determine the period of the motion?
ii) Determine the net mechanical energy of the system?
iii) Determine the maximum angular speed of the object? At what point in the motion does this take place?
iv) Determine the highest angular acceleration of the object? Determine at what point in the motion does this take place?
