Question 18 Three forces of equal magnitude are applied to a 3-m by 2-m rectangle. Forces F₁ and F₂ act at 45° angles to the vertical as shown, while force F3 acts horizontally, as shown in the figure below. The torque of F1 about point Cis: F₁ A B 0 45°! clockwise counterclockwise C 450 1 pts F₂
Question 19 Three forces of equal magnitude are applied to a 3-m by 2-m rectangle. Forces F₁ and F₂ act at 45° angles to the vertical as shown, while force F3 acts horizontally, as shown in the figure below. The torque of F2 about point C is: A F₁ B 45°! counterclockwise O clockwise C 45° F3 1 pts F2
Question 20 Three forces of equal magnitude are applied to a 3-m by 2-m rectangle. Forces F₁ and F₂ act at 45° angles to the vertical as shown, while force F3 acts horizontally, as shown in the figure below. The net torque about point B is: A B F₁ $45°1 O clockwise counterclockwise C 45° F3 1 pts F2
