1) assuming no slipping and when starting from horizontal cable (θ = 0o) the spool moves to the left- determine the minimum tension in the cable (Tmin) that causes the spool to slip. Assumeμk = 0.4 and μs = 0.5.
The 186-kg wheel has a radius of gyration about its center O of ko = 300 mm, and
radius r = 0.4 m. When the wheel is subjected to the constant couple moment M =
92 N.m, it starts rolling from rest. Determine the average friction force that the
ground applies to the wheel if it has been rolling without slipping. Please pay
attention: the numbers may change since they are randomized. Your answer must
include 2 places after the decimal point, and proper Sl unit. Take g = 9.81 m/s².
