5. The arms of a Porter governor are 300 mm long. The upper arms are pivoted on the axis of rotation and the lower arms are attached to the sleeve at a distance of 35 mm from the axis of rotation. The load on the sleeve is 54 kg and the mass of each ball is 7 kg. Determine the equilibrium speed when the radius of the balls is 225 mm. What will be the range of speed for this position, if the frictional resistances to the motion of the sleeve are equivalent to a force of 30 N? [Ans. 174.3 r.p.m. ; 8.5 r.p.m.]
For the problem related to Fundamental.6 sketches of the system showing: • the respective velocity and acceleration and the frame of reference considered • the forces acting on the system of considered, in other words, a free body diagram (FBD) are mandatory. Their absences will automatically make the problem false. F The 77-kg man pushes on the 120-kg crate with a horizontal force F. The coefficient of static friction between the man's shoes and the surface is 0.82. What must be the coefficient of kinetic friction between the crate and the surface if we observe an acceleration of the crate of 2.1 m/s²? Type your answer in the cell below.
Let’s use an overly simplified model to investigate the difference in side impact safety between a convertible and a regular car. Specifically, we consider the side panels and the roof panel as beams, each with length L, second-area moment I, cross-section area A, and Young’s modulus E. Derive the spring rate k for the convertible. (k = F/δ, where δ is the deflection due to F.) Derive the free-body diagram for the regular car. Derive the spring rate for the regular car, by assuming that the horizontal beam does not buckle. Note: Need to take into account the compression of the horizontal beam.
