A uniform board of length 90 cm is pivoted at a hinge at one end. It is kept level by an upward vertical force T applied at the opposite end. The weight of the board is 6N. Take moments about the hinge to find T, when the board is level. The hinge exerts an upward force, F on the board. Equate parallel forces to determine F when the board is level. All inputs in understanding this question and the steps to solve it will be great help. Thank you.
