Expert Solution

Step 1

In this question there are 6 sub-parts.

As per the company's policy we can only solve first 3 sub-parts.

I'm doing sub-part a, b & c.

Please repost others as a seperate question.

In a statically indeterminate structure the number of equilibrium equations are insufficient for determining the internal forces and reactions on support.

r = no. of reactions

n = no. of members

r = 3n = determinate

r > 3n = indeterminate

r < 3n = unstable

For roller/rocket support, r = 1

For hinge support, r = 2

For fixed support, r = 1
