Determine the magnitudes of all the pin reactions for our frame.
00:06
So for our frame, we can let the sum of all of our forces in our x direction be equal to zero.
00:13
So from this, we get ax is equal to bx.
00:19
Now, from our sum of all of our forces in our y direction, we have force is equal to ay plus by, and our net torque, t -net, is equal to zero.
00:31
Let's consider our moments about part a.
00:36
So considering our moments, we get by times a cosine of theta plus bx times a sine of theta is equal to f times a plus b cosine of theta.
00:50
Now for our bd expression, we have the sum of all of our forces in our x direction is equal to zero.
00:57
So we get bx minus dx is equal to zero.
01:00
And in our y direction, we get d -y minus b -y is equal to 0...
