A3. A seesaw of uniform density is 2 meters in length with a mass of 40 kg. It rotates about a point that is 0.75 meters from the left end. One 32 kg student sits on the left end applying for F1. Fs the gravity of the seesaw. A second student with mass of 21 kg sits a distance x from the axis of rotation. F2 a) Set-up the conditions for equilibrium (ALGEBRA ONLY HERE!!!). That that sum of the torques is zero and that the sum of the forces in the y- direction is also zero. Note the axis of rotation is designated by the triangle in the diagram. b) Determine the distance x from the axis where the second student sits for equilibrium. c) What is the normal force? d) A scaffold of mass 50 kg and length L is supported by a Tension of 427.1 N at an angle of 35°. Use equilibrium of force in the x- direction to determine the x-component of the wall's Normal force. 24 Fs e) Use equilibrium of force in the y-direction to determine the y-component of the wall's Normal force. What is the angle of the Normal force? A3. A seesaw of uniform density is 2 meters in length with a mass of 40 kg. It rotates about a point that is 0.75 meters from the left end.
