Question
a 10kg board is attached to the wall on the left with a hinge. A 20kg mass sits on the board, 0.8meters from the left edge. A cable is attached to the right edge of the board; the other end of the cable is secured to the ceiling. What is the tension T in the cable?
Please show step by step math
I know the equation is set up
-20g*.8-10g*.6+Tsin35*1.2 correct?

applying summation of moment=0
-20g*.8-10g*.6+Tsin35*1.2 ya it is correct
T=313.55 N ans
