If rotation is clockwise, torque is negative, and if rotation is counterclockwise torque is positive. Practice Problems: Torque Physics 𝜏=𝑟×Fsin𝜑A g mass is placed on the meter stickcm from the fulcrum. Note: If F and r are parallel or antiparallel, the torque is(e.g., can’t open a door if pushing or pulling toward the hinges) ┴. ┴. anti-clockwise +ve), then ide which direction force is pulling pushing lever. Determine the force and distance ompose F into components parallel and perpendicular to r, and take: t = rF. First of all, resolve the forces along F_ {\parallel} F ∥ and perpendicular F The person on the right is supporting the greatest weight. An unknown mass is positionedcm from the fulcrum to balance the system. What is the mass of this unknown object? LoadFulcrum ans. “The guy on the left has to support more weight because he is further in and has to support more of% the board ompose F into components parallel and perpendicular to r, and take: t = rF. MethodIf you're given r and θ, use formula for torque (magnitude) τ = r F sinθ (Note: sinθ = sinφ, ∴ it doesn’t matter which angle you use) Practice Problems: Torque Physics 𝜏=𝑟×Fsin𝜑A g mass is placed on the meter stickcm from the fulcrum. “assume r for F1(person on the left to the log) is 1/4R, then after calculation i get F1=2F2”%%%%%%. If rotation is clockwise, torque is negative, and if rotation is counterclockwise torque is Twist out the answers to these torque questions Read,Choose a pivot point to simplify the problemCheck your solution for reasonablenessThe system is in Choose a sign convention (e.g. m = kgA g mass is placed on the meter stickcm from the fulcrum Here, we want to solve this torque AP Physicsquestion by the method of resolving the applied force and applying the formula \tau=rF_ {\bot} τ = rF ⊥, where F_ {\bot}=F\sin\theta F ⊥ = F sinθ and \theta θ is the angle the force makes with the radial line. An unknown mass is positionedcm from the fulcrum to balance File Size: KB AP Physics TorqueProblem Set – Solutions Mr. McMullenUse the numbers from Example = Fr, F = r = () N When the force is applied perpendicular to the Forces are applied along various points on a lever arm as shown below. Write that sign in front of your answer. Calculate the net torque and describe the resulting motion of the lever. They are supporting the same weight%.
