Rule

Divide the product of the weight and its distance from the nearest end or support by the whole length, and the quotient will give the pressure upon the end or support farthest from the weight.

2. Divide the product of the weight and its distance from the farthest end, or support, by the whole length, and the quotient will give the pressure upon the end or support nearest the weight.

Example

What is the pressure upon the supports in the case of the preceding example?

1500X2 1500X8 --------=600 lbs. upon support farthest from the weight;---------900 lbs.

6 6 upon support nearest to the weight.
