Re: Physics Quiz 5


No, not quite that easy. But not too much harder. The vehicle is in static equilibrium. The wheels are not accelerating. Therefore, the net torque on each wheel (in the plane of the wheel) must be zero. Your solution does not satisfy this physical requirement.

A)
Fy=Fx=(T*sqrt(2))/(2r)
and
F=T/r

B)
T=μNr


Work:
Part A:
T=Fr
(F is the same as force applied by vehicle)
T/r=F
Because the wheels are in a square, theta (here "x") is 45degrees:
Fy=Fx=Fcos45=Fsin45=F(sqrt(2)/2)

Part B:
F=μN
T=FR
T=μNr
