What is the maximum normal stress in the beam and where is it located? The beam is 1m long, 0.2m high, and 0.05m thick (out of the page). The Modulus of Elasticity is 100Gp. The force is applied at an angle of 20 degrees with horizontal.
| |- - - - -- - (Imaginary horizontal)
|____________| -- 20deg
(the picture is kind of messed up but just imagine a force being applied 20 degrees downward of the horizontal out of the end of the beam, so pretty much straight out of the end of the beam but at a slight angle.
The Attempt at a Solution
I calculated that it is 1.879N in x direction and .684N in y direction and that sigx is 187.7 N/m^2
Everywhere I see makes it look like i use equation My/I but I do not know how to calculated y or I and I do not know how any of that plays into this.
Any help would be awesome
