Figure shows a section of an alpine cable-car system. The maximum permitted mass of each car with occupants is 2800 kg. The cars, riding on a support cable, are pulled by a second cable attached to each pylon. What is the difference in tension between adjacent sections of pull cable if the cars are accelerated up to 35° incline at 0.81 m/s 2 ?

Question

Jitender Pal · Answer

The magnitude of the weight of the trolley can be calculated by multiplying the mass of the trolley and the acceleration due to gravity.

Rounding off to 2 significant figures,

Therefore the magnitude of the difference in tension between adjacent section of pull cable is 1.8 x 10⁴ N.
