" "But there isn't anything q-q-queer about this, Steve," protested Toby.

2 lengthens, Q increases, and the frictional resistance on the surface of the pulley increases, both in consequence of the increase of Q, which increases the pressure on the pulley, and of the increase of the coefficient of friction.

If the pulley turns with left-handed rotation, the friction would carry the strap toward the left, unless the weight, Q, were greater than P. If the belt does not slip in either direction when the pulley rotates under it, then Q-P exactly measures the friction on the surface of the pulley; and V being the surface velocity of the pulley (Q-P)V, is exactly the work consumed by the dynamometer.

" "G-g-guess you're about r-r-right, Steve!" declared Toby Jucklin, instantly; "to t-t-tell you the t-t-truth, I've been squinting that same p-p-patch of white myself q-q-quite some little time now.
