## Question:

The uniform wood block is released from a {eq}30^o {/eq} angle from its vertical position. A separate "identical" wood block is provided for use in determining mas of the wood block.

Determine:

a) Reaction as the pin.

b) Angular velocity of the wood block at impact with the spring,

c) Angular acceleration of the wood block at impact with the spring,

d) Spring constant {eq}(k) {/eq}.

## Reaction Force:

If an object is supported by some kind of support, then the support offers a reaction against the force which is applied on the body. This force is called reaction or reaction force which depends on the type of support.
