The stresses in the various members due to a vertical panel loadof one pound are given. To obtain the stress in that member dueto any other vertical panel load, multiply the stress here given by thevertical panel load. For example, if the stresses in VJj^^ (Fig. 24) or LJj^ (Fig. 31)due to a panel load of 3 000 pounds, were required, they would bedetermined as follows: U^ L^ (Fig. 24) 3 000 X - 1. 73 = - 5 190 Li (Fig 31) 3 000 X + 5. 00 =+ 15 000 pounds These diagrams are especially useful, since it is the custom ofmany engineers not to compute the stresses due to wind, snow, and 234.
