A bicycle pedal is pushed by a foot with a 60-N force as shown. The shaft of the pedal is 18 cm long. Find the magnitude of the torque about $ P $.
about this question. A bicycle paddle is pushed by a food with 16 Newton Force. So this is the force and the shaft of the battle is 18 centimeter long. So this is the shaft of the battle, which is 18 centimeters. You need to find the magnitude of the talk about people. So the magnitude of the torque is going to be our across F. So R cross F means we have our F. Scientist to, so we are looking for the angle between the force and uh, and the R factor. So this is the are backed up. This is the our vector. And clearly the angle between them is 70 plus 10. So r is the distance, which is 0.1. It, because it should be written in meters. So that's 18 oh 400. That's, that's also, we can write as 18 and 100 F is given us 60 newtons and the angle has given us 70 Plus 10. So that's where I'm going to plug in of my numbers in the calculator. So 18 times 60 over 100 times sine 80. So, uh, that's going to come out as 10.64 newton meters. So this is a required talk. Thank you
