A minimum moment $M$ is required to begin rolling the uniform cylinder of radius $r=170mm$ and weight $W=880N$ over the

obstruction of height $h=43mm.$ There is sufficient friction to prevent slipping of the cylinder at the contact points. Answer the following

questions when the applied moment is just sufficient to begin rolling the cylinder over the obstruction.

The magnitude of moment M $($in Nm $)$ is

One possible correct answer is: $99\mathrm{.}447787305701$

The magnitude of reaction force at point $A($in $N)$ is

One possible correct answer is: $0$

The magnitude of the net resultant reaction force at point B $($in N $)$ is

One possible correct answer is: $880$
