Aufgabe 19: Stab rutscht ab von Tischkante (Meriam [7]) The uniform slender bar of mass m and length l is released from rest in the vertical position and pivots on its square about the corner at O. (a) If the bar is observed to slip when > = 30, find the coefficient of static friction s between the bar and the corner. (b) If the end of the bar is notched so that it cannot slip, find the angle at which contact between the bar and corner ceases."[7] 0 ation mum sponding MO Figure 7.7: Stab rutscht ab von Tischkante
