## Homework Statement

A man of mass mm = 95 kg decides to paint his house. To do this, he builds a platform using a uniform beam with a mass of mb = 100 kg and a length of L = 7 meters. The beam is supported by two sawhorses, as shown in the diagram above.

a)

If the man stands over the support at point B, calculate the force exerted by the beam on the support at A.

F = 490 N

b)

x =

c)

Number of cans =

## Homework Equations

For part b, we'd solve for x: (some length) * m = xM

I don't understand where to go for part c.

## The Attempt at a Solution

I said (some length) was 1.5 and tried to multiply by 95 and divide by 100, and I keep getting the wrong answer. I don't know where to go for parts b and c.
