Answer 2

Hi I got a physics question and would like you to help me abit urgent. I have a device that has to climb a pipe of 105mm in diameter. I have the basic concept of my device I just need to know a few things, the device has 4 wheels acting on the inside wall of the pipe it has to climb up 2.5 meters then come down pulling a chain of 0.2 kg/m the tube is set 0.5 meter above the ground, so the chain will need to be carried up all the way to the top. So 3 meters in total minus the height of the device which is 20cm. The chain is attached to the bottom 1. What force should the wheals act on the inner walls 2. what force is pulling it down 3. what motor is right to be used to pull the device and the chain, the device weight roughly 370 g without the motors. Thanks you
