Two components of the force F:
F⒳= Fsinθ = F(fr)
F⒴ = Fcosθ= N
F(fr) = μN
Fsinθ =μFcosθ
tanθ=μ=1.12
θ=arctan1.12=48.24°
The person in the drawing is standing on crutches. Assume that the force exerted on each crutch by the ground is directed along the crutch, as the force vectors in the drawing indicate. If the coefficient of static friction between a crutch and the ground is 1.12, determine the largest angle θMAX that the crutch can have just before it begins to slip on the floor.
I wasn't able to copy the picture too. So just use your imagination! Tried this one for at least 45 minutes!!
