The preloads of the M10 bolts used in a pressure vessel are applied with the wrench shown. For the 16,500 N preload force, Fi, the required torque, T, is approximated as T=K*Fi*d where K-0.20 and d is the nominal bolt diameter. The required torque is developed by applying a force to the end of the wrench as shown. The wrench material is AISI 1035 steel, forged and heat treated. For the applied force, determine the critical failure spot for yielding...

A wrench is used to apply a torque on a bolt as in the picture
below.
ALL 6 forces that act on the bolt are
equal in magnitude. All 6 forces are applied at the same time. If
d=0.3 [m] and F1=F2=F3=F4=F5=F6=50[N], what is the torque around
the center of the hexagonal bolt? You may use the diagram

1. Suppose a torque T is generated by applying a force F to a wrench. The force is applied some distance L from the bolt that the wrench is tightening. If the force applied is reduced to a quarter of the original force, and the new torque generated is 3T, at what distance from the bolt is this new force applied? 2. Two extended bodies, object 1 and object 2, are left to roll down an incline from an initial...
