F1 + F2 = (M1 + M2)* g

M1 is the beam mass. M2 is the student's mass.

F1 is the force on support 1.

F2 is the force on support 2.

Now write a moment balance equation, such as.

M2*g*2 + M1*g*1.5 = F2*3

You can solve the last equation for F2 directly. Then use the first equation to solve for F1.
