 For, first, suppose that while the horses are pulling at the stone the traction-engine is applied to the opposite side of the stone, so as to pull the stone with the same drawing-power as that of the horses. Then the force exerted by the engine will counteract...  Elementary statics - Σελίδα 13των James Hamblin Smith - 1871 - 130 σελίδεςΠλήρης προβολή - Σχετικά με αυτό το βιβλίο
