pucesnail473Lv1in Mechanical Engineering·22 May 2023the picture shows a plank, which is 5 m in length, supported on two trestles. The mass of the plank is 37 kg and the mass of the Electrician is 70 kg. In order to change a lightbulb on a stairwell the electrician has to position themselves at point A, as shown on the picture. To stop the plank tipping, the electriciant attaches weights to a rope at point B. a.Draw a diagram showing all the forces acting on the plank and the distances from point B that each force acts. b.State, in words, two conditions that must be satisfied for the plank to be stationary and stable. c.For each of the two conditions you have identified in part (b), using the information contained in your diagram, write an equation that must be satisfied for the bar to remain stationary. Do not include units in your equations. d.What is the minimum weight (in newtons) that the electricain must attach to the rope to prevent the plank from tipping? (Hint: think about the reaction forces at the trestle nearest the rope at the point when the plank just begins to tip.) Give your answer to 2 significant figures. e.If the rope has a diameter of 22 mm, calculate the stress in the rope when applying the force you calculated in part (d). Give your answer to 2 significant figures. The acceleration due to gravity, g, is assumed to be 9.8 m s-2.

beigedeer154Lv1in Mechanical Engineering·13 Oct 2022A 20 kg crate is subject to a force having a constant direction and magnitude of F = 100 N (Figure 2). The crate is moving to the right with an initial speed of 8 m/s. Determine its speed when s = 21 m. The coefficient of kinetic friction between the crate and the ground is μk = 0.25.
