A uniform beam of weight `W` is attached to a verical wall by a hings `H`. The beam is held hotizontal by a rope as shown below.

Which one of the following best shows the direction of the reaction force `R` at the hings?

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
A
FBO of rod
For rotational equilibrium net torque about COM of beam should be zero and for translational equilibrium net force must be zero.

A cylinderical container of length L is full to the brim with a liquid which has mass density rho . It is placed on a weight scale, the scale reading is w. A light wall ball which would float on the liquid if allowed to do so, of volume V and mass m is pushed gently down and held beneath the surface of the liquid with a rigid rod of negligible volume as shown on the left Q. if instead of being pushed down by a rod, the ball is held in place by a thin string attached to the bottom of the container as shown on the right what is the tension T is the string?

A uniform thin cylindrical disk of mass M and radius R is attaached to two identical massless springs of spring constatn k which are fixed to the wall as shown in the figure. The springs are attached to the axle of the disk symmetrically on either side at a distance d from its centre. The axle is massless and both the springs and the axle are in horizontal plane. the unstretched length of each spring is L. The disk is initially at its equilibrium position with its centre of mass (CM) at a distance L from the wall. The disk rolls without slipping with velocity vecV_0 = vacV_0hati. The coefficinet of friction is mu. The centre of mass of the disk undergoes simple harmonic motion with angular frequency omega equal to -
