## Homework Statement

There is a copy of the problem in the picture with the graph.

## Homework Equations

M =

**F***d, M =

**F**x

**r,**

F_x =

**F**cos(theta), F_y =

**F**sin(theta) where theta is measured off the positive X axis,

## The Attempt at a Solution

I tried splitting the force vector into X and Y components and then multiplying each of those by the perpendicular distance to the corresponding axis. My understanding from in-class examples was that these two values should sum to the moment about the given point. All I know is that I get the wrong answer:

M = 1*30cos(26.57) + 4*30sin(26.57) = 80.51

According to my book, I should get 83.2. Any help is greatly appreciated!
