Help me please The force-torque system acting on O is equivalent to the key acting on A. If R = 600i + 1400j + 700k lb and | C | = 1200 lb ⋅ pie, determine CR
(Figure 1) shows a uniform 2.0 kg rod that can pivot in a vertical plane on an axle. We want to find the net torque about the axle. For each of the four forces F 1→1, F 2→2, Fgrav→ and F axle→, is the torque about the axle positive (+), negative (-), or zero (0)?
Two disgruntled businessmen are trying to use a revolving door, as shown in the figure. The door has a diameter of 2.60 m. The businessman on the left exerts a force of 647 N perpendicular to the door and 1.1 m from the hub's center, while the one on the right exerts a force of 803 N perpendicular to the door and 0.696 m from the hub's center. Find the net torque on the revolving door. (Indicate the direction with the sign of your answer.) N · m
The body in the figure is pivoted at O. Three forces act on it in the directions shown: FA = 8.10 N at point A, 5.60 m from O; FB = 16.0 N at point B, 3.90 m from O; and FC = 18.0 N at point C, 3.50 m from O. Taking the clockwise direction to be negative, what is the net torque about O?
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) / d
