19. Component ABCD supports two independent loads W₁~ N(150, 5²) lb and W₂ ~ N(550, 7.5²) lb. Determine the distributions of x and y components of the force acting on pin A.

Solution

Therefore, we can obtain:

Also, we have:

And,

Thus, we can obtain:

Finally, we have A_x ~ N(2620.4, 33.23²) lb and A_y ~ N(1920.4, 34.43²) lb. Ans.
