The machine shown is designed as an overload protection device which re-
leases the load when it exceeds a predetermined value T. A soft metal shear pin
S is inserted in a hole in the lower half and is acted on by the upper half. When
the total force on the pin exceeds its strength, it will break. The two halves then
rotate about A under the action of the tensions in BD and CD, as shown in the
second sketch, and rollers E and F release the eve bolt. Determine the maximum
allowable tension T if the pin S will shear when the total force on it is 800 N.
