A bolt is primarily designed to withstand tensile loading while clamping components together. Ideally the bolt should only be loaded in tension. Any forces tending to slide the clamped components laterally should be withstood by separate means.. ... The total vertical force on each bolt F tv = F nv + F nm. h n / Sqrt(h n 2 + v n 2) The total.
F R = 1290 lbs R 1 = 1270 lbs R 2 = 2790 lbs In other words, the combined force from all clamps on the right side must be greater than 1290 lbs. We recommend a 2-to-1 safety factor (2580 lbs). Even though F L (the
Any help would be greatly appreciated. The last formula I found is this: T = (C x D x P x A) / (no of screws) T = torque per screw (Nm) C = torque coefficient; generalized values for copper/mild steel (0.36 dry, 0.18 lubricated) D = nominal screw size (m) P = desired Pressure (force per unit area) (N/sq m) A = surface area (sq mm)
Then we the sandwich will shrink by releasing some of the preloaded tension on the bolts until there is equilibrium, meaning the leftover tension in the bolts is balanced by compression force by the rubber. In our case for each incremental shrinkage in the bolts, it will compress the rubber by $1/ (2/3)=1.5\delta_s$.
Bolted Joint Torque Explanation and Calculation We are often asked what torque value should be used with a specific nut/bolt assembly. First, it’s helpful to understand that torque is a rotational force that is equal to a linear force times the distance of that force from the center of the rotational axis.
