## Homework Statement

Need help at

*"Forming an equation based on the fact that all the vertical forces must be in equilibrium"*. I'm to calculate the reactions at the supports A and B by doing:

**(i) Forming an equation based on the fact that all the vertical forces must be in equilibrium**

(ii) Taking moments about A to find the reaction at B

(iii) Using your value for the reaction at B in the equation formed in part (i) to find the reaction at A

(ii) Taking moments about A to find the reaction at B

(iii) Using your value for the reaction at B in the equation formed in part (i) to find the reaction at A

## Homework Equations

I thought that the equation that I need to form would have been an equation for finding moments,

*moment = force x distance.*## The Attempt at a Solution

For part

**(i)**I done:

**M = (-30 x 0.5) + (-25 x 2.5)**

= -77.5

= -77.5

It states that they are in equilibrium so does that mean I need to add '

**(30 x 0.5) + (25 x 2.5)**' to the equation so that it become an equilibrium? Or is what I'm doing for part

**(i)**actually what I should be doing for part

**(ii)**as I need to take moments for that section of the question? If so then what equation must I form for part

**(i)**?
