- The answers are provided; please explain the purpose of each equation and why they were used Consider a bar of length 5.5 m, being acted on by three forces and constrained to rotate about its left end. The magnitudes of the first two forces are 19 N and 28 N and the first force is acting on the end of the bar at an angle of 43° What is the torque in newton-meters, due to F1 on this bar relative to the left end? Ans. = 78.87 Nm Equation used: τ1 = rFsinθ What is the torque in newton-meters, due to F2 on this bar relative to the left end, if this force is acting at the midpoint of the bar? Use a coordinate system with positive directed out of the screen. Ans. = 77 Nm Equation used: τ2 = F2 x (L / 2) What is the magnitude of the force F3, in newtons, if the force is a distance 0.85 m from the left end and the bar is not rotating? Ans. = 183.38 N Equation used: F = (τ1 + τ2) / dNeeds Complete typed solution with 100 % accuracy.Please asap
- Can you help me with a physics problem?There exists a uniform rod with a L length and a m mass that is held to a wall by a frictionless hinge at its base and by a horizontal string at a x distance from the hinge. See picture. 1. What is the tension in the string and the horizontal and vertical components of the hinge's force?2. Theoretically, if the string were to be cut. What would the angular acceleration of the rod be just after it has been cut?20kg mass is at the 1.25 meter mark. Package G is at 1 meter mark. What must the mass of object G be? Calculate the torque that each object creates. The 20 kg mass on the left creates a positive torque.
