The elements of the mechanics of materials and of power transmission (1911)

load Wto move from left to right. W (L — x)By moments about the right support we find Ri = —^^ • While the load is between the left support and some section adistant r from the support, the bending moment is M = Rir-W(r-x) = ^ ^^~ ^^ - W{r-x) = Wx{i-j)^ This result must be positive, since r is less… … When the load passes section a and moves toward the rightsupport, the bending moment at a becomes R^r and decreasesin value, since i?i becomes less as W approaches the right sup-port. When W reaches the right support, Rx becomes zeroand the bending moment at a becomes zero. The bending…
