The maximum bending moment will evidently occurat one of the supports and is equal to the algebraic sum of thetwo moments at the support, or, Bince the loads are symmetrical M = M1 + Mg = - 15150 - 2490= - 17640 lb. in. Assuming a diameter of 2 inches and substituting the known values of M and d in (14) we have o - 32 x 17640 _ ooe;nn 1V / , S = - 22500 lb./ sq. in. o BEARING.- The bolt must be investigated for crushing andshear, hence, dividing the pressure by the area we have for thestresses —_= 11560 lb./ sq. in.c 1.5 x 2 34700 Ss = 5.14 = 11°00 lb./ sq. in.These values are safe for a toggle boltTthe relative motionbetween the surfaces in contact is slight and the speed is slow.

It is eccentrically loaded,hence, assuming a section as shown in Fig. 13 and investigatingthe section, we find that the section has the properties tabulated -30- in Table VII. L //
