PhysicsEasysingle choice

Consider the given system of mass m and spring constant $k$ . Find the maximum value of $b$ so that system performs SHM. Neglect the mass of connecting rod.

Options:

Answer:

Solution:

Restoring torque

$τ = {ka}^{2} θ - mgb θ = ({ka}^{2} - mgb) θ$

For SHM, ${ka}^{2} - mgb \geq 0$

$b \leq \frac{k a^{2}}{m g}, b_{max} = \frac{{ka}^{2}}{m g}$
