Extracted text: Sample Problem 4/7 120 36 60 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. B. 50 Dimensions in nillimeters
