a) Calculate the total force required to accelerate the tram uniformly form 18km/h for one minute over a distance of 750 meters up an incline 1 in 150. b) What is the maximum power developed by the locomotive under those conditions? c) Calculate the angular velocity of the wheels under conditions of maximum power is found to be 191 rev/min. What toque is the locomotive developing and what is the diameter of the driving wheels? NB: Show a detailed space diagram in your solution (a

Learning Goal: Use the general equations of motion for plane motion to determine the initial acceleration of a spool. A spool has an outer radius R = 380 mm, an inner radius r = 210 mm, a mass m = 90 kg, and a radius of gyration KG = 320 mm. A rope is wrapped around the inner radius and pulled to the right as shown in (Figure 1). The coefficient of static friction between the spool and the ground is us = 0.2. The coefficient of kinetic friction is k = 0.15. Figure R A P 1 of 1 Part A Draw the free-body diagram for the spool, assuming the friction force acts to the right. Draw the vectors, starting at the black dots. The location and orientation of the vectors will be graded. The length of the vectors will not be graded. + 0 No elements selected Select the elements from the list and add them to the canvas setting the appropriate attributes. Submit Request Answer
