1. The problem statement, all variables and given/known data A thin sheet of metal is pivoted at one corner (the origin) and it's free to rotate about the origin in the xy plane. It has sides of 1.6m and 1.2m. two forces f and -Mgj are acting on the sheet of metal. f acts parallel to the x-direction (in the minus direction) and -Mg is the force due to gravity which acts downwards through the centre of the metal sheet. Find the total torque at origin due to these forces and hence determine what for what force f the sheet metal is balanced so that it does not rotate around the pivot point when the sheet has a mass of 0.5Kg. 2. Relevant equations T=r.f Torque is the force applied by the distance from the pivot point in this case. 3. The attempt at a solution using pythagorus i get that f acts at 4 units away from the origin and -Mg acts at 2 units away. I can calulate the torque that -Mg is applying but no value is given for the force f so i cannot add these together. Help please!!
