Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.

Consider a bicycle’s 20 cm diameter gear with a 18 cm crank arm going out to the pedals. So the chain is going around this gear and the person is pushing on the pedals, going from 60 rpm to 90 rpm in 10 s (assume at a constant rate). What is the tangential acceleration of the pedal and what length of chain passes over the top of the gear in this time?

I am having trouble with a 3 d motion problem. The problem is as follows, "A point on a rotating turntable 20.0 cm from the center accelerates from rest to a final speed of 0.600 m/s in 1.80 s. At t = 1.29 s, find the magnitude and direction of each of the following." The problem asks me to find the radial acceleration, the tangential acceleration, and the total acceleration of the point. Thanks for the help.
Hi, today I had my engineering mechanics 1 test which I completely screwed up. I was quite confident in the uniform circular motion, but I had this problem in my exam which completely confused me. When I read "upward vertical acceleration" my head just start to spin as I couldn't understand what force could cause an upward acceleration. Could you help me with this problem? I bet it is easier than it looks, but still, I am confused about what is asking me and most importantly about the input it is giving me. I don't have my exam paper with me, but on my body diagram, I knew that on the aeroplane were exerted the Force of Contact Fn1 and the Force m1g in the y opposite direction. On the pilot was acting the Force of Contact with the seat of the aeroplane Fn2 and the m2g in the y opposite direction. Here is the problem: During an air show an aircraft comes out of a dive at the bottom of a circular arc at a horizontal speed of 97m/s. In the cockpit the aircraft pilot of mass 58kg…
