1. The problem statement, all variables and given/known data Find the other forces present. Assume the triangle to be weightless 2. Relevant equations τ=Force x perpendicular distance 3. The attempt at a solution The force,10N provides a 50Nm Torque. (10 x 5) The triangle is in equilibrium so,anticlockwise moment is equal to clockwise moment 50Nm=2 x F F=25N at p But within the two meters,not only p touches but other parts of the triangle(in contact with the wall) touches too. Should I account for that? As the net force should be zero,pivot point exerts a force of 25N to the left.and 10N upwards. Is this correct?
