Tram - safe downhill

What is the maximum angle at which the tram can go downhill to still be able to stop? The coefficient of shear friction is f =0.15.

Final Answer:

α =  8.5308 °

Step-by-step explanation:

f=0.15  f > Fy:Fx = tan α  f > tan α   α < arctg f  α1=arctanf=arctan0.150.1489 rad  α=α1  °=α1 π180   °=0.1489 π180   °=8.531  °=8.5308=8°3151"
