A uniform rod of mass 2M is bent into four adjacent semicircles each of radius r

in the arrangement shown in fig.4.191 at a particular instant.the roller is coming down with a speed of 12ms-1 and C is moving up with 4ms-1.as the same instant it is also known that w.r.t pulley p block A IS MOVING down with speed 3ms-1 determine the motion of block b (velocity)w.r.t ground A uniform [...]

A bead of mass m is attached to one end of a spring of natural length R and spring constant K=R(3​+1)mg​. The other end of the spring is fixed at a point A on a smooth vertical ring of radius R as shown in Fig.6.301 The normal reaction at B just after it is released [...]

Consider the moment of inertia I of the rigid homogeneous disc of mass M as shown in the figure about an axis through its center (different shadings only differentiate the two parts of the disc each with equal mass M/2 ). Which one of the following statements concerning I is correct? A uniform rod of [...]

A uniform rod of mass 2M is bent into four adjacent semicircles each of radius r, all lying in the same plane. The moment of inertia of the bent rod about an axis through one end A and perpendicular to plane of rod is. A uniform rod of mass 2M is bent into four adjacent [...]
