## Homework Statement

what is the down force on the connecting rod?

i tinnk ive work most of it but i'm a bit unsure of what to do next?

A train of mass 138800kg

have 24 wheels (12 axles)

V = 37.1 m/s

U =0

s= 694 m

F= 12.1KN

R = 0.4 m

r = 0.21 m

## Homework Equations

V2 = U2 + 2 x a x s

Average braking force for the whole train = m x a

## The Attempt at a Solution

a = -0.99m/s

Average braking force for the whole train 138800 x -0.99 = 137KN

braking Force for each wheel 137/24 = 5.7KN

__so this is were i need the help please__

Were is this braking force atchley acting on the wheel ( at the rim the edge of were?)

when the force F is clamping on the wheel the force from the wheel will transfer to the rod?
