Problem description: A mine skip is going to be designed. The gross expected mass is 5500 kg. This mine skip is pulled by a cable attached to a rotating drum through the mine tunnel. The cable system includes a mechanism to enable attaching it to the vehicle parallel to its datum. By meteorology, some coordinates on the passage way have been picked up. If the drum is rotating with a constant angular velocity of=200 rpm, and its radius is 600 mm, find variation of the torque applied to the drum and the variation of the normal force applied to the undercarriage of the vehicle when it moves between points A and B. The kinematic friction coefficient can be taken as 0.34. d Y 14 A 1 Qw st of 5 60 70 00 8 20 9 10 11 12 13 B X # A 1 2 3 4 X (m) 0 6 12 18 24 Y(m) 0 -0.8 -1.5 -0.4 0.5 # 8 9 10 11 12 X (m) 48 54 60 66 72 Y (m) 0.66 -0.2 -0.64 0.16 1.34 30 0.96 13 78 1.96 36 1.54 14 84 2.24 7 42 1.24 B 90 2.44 Requirements: 1- Model the passage way by mathematical equation(s). 2.
