sorry for my unclear pic. r is the distance from the center of the wheel to the point which the rod acts R is the effective wheel radius. the top of the rod it fixed to the braking braket. the down force on the braket is what is needed?

sorry what do you mean by both will be added?

i did think torques but all i can think is t = f x r so is this 5.7 x .21 =1.194 KN/M Whats that in a straght down force on the rod?

Homework Statement what is the down force on the connecting rod? i tinnk I've 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 =...
