Question

A slider crank mechanism has slider mass of 10 kg, stroke of 0.2 m and rotates with a uniform angular velocity of 10 rad/s. The primary inertia forces of the slider are partially balanced by a revolving mass of 6 kg at the crank, placed at a distance equal to crank radius. Neglect the mass of connecting rod and crank. When the crank angle (with respect to slider axis) is ${30}^o$, the unbalanced force(in newtow) normal to the slider axis is

Answer 1

Given:
$m_p=10kg,m=6kg,r=0.1m,\omega =10rad/s,\theta ={30}^o$


$r=\frac{s}{2}=0.1m$
Unbalanced force $=m{\omega }^{2}rsin{30}^o$
$=6\times 100\times \times 0.1\times \frac{1}{2}=30$ N
