What reading level is Strength of Material An Elementary Study Prepared for the Use of Midshipmen At book?
To quickly assess the difficulty of the text, read a short excerpt:
What is the maximum stress?
Ans. 804J Ibs. Per sq. In.
CHAPTER VI.
SHEARING STRESS IN BEAMS.
31. In the preceding chapters we have made use of the simplest kinds of loads. In tension and compression we can vary the intensity of the stress only by increasing or dimin- ishing the load as it has already been applied; in torsion also we can change the value of the twisting moment only by vary- ing the amounts of the forces forming it or by changing the length of the arm; but to get the stresses due... to bending and shearing we can apply loads in a number of different ways. We have also been neglecting the action of the force of gravity on our rod, which is of importance, as in the case of large shafts or beams whose bearings or supports must be spaced with reference to their weights; besides the supporting forces' for a beam loaded in any way must be known in order to find the shearing and bending stresses.
32. Obviously, as we have assumed in Chapter IV, the supporting forces for a weightless, horizontal beam, loaded W with a weight, W, exactly at its middle, are each, or half t the load; if, however, we take into consideration the weight of the beam and put several loads upon it at different places, the conditions of equilibrium require that the sum of the moments of all the forces acting on the beam about any axis must be zero.
