An 80 kg pilot is traveling at a constant speed of 40 m/s. Determine the normal force she exerts on the seat when she is upside down at A on the vertical loop that has a radius of 100 m.

Aforce of 40n applied at the end of length 4m and diameter 2.00mm process and extension of 0.24mm,calculate the stress on the wire, strain in the wire and the young modulus for the material of the wire
