Σελίδα 28 - NEWTON'S FIRST LAW OF MOTION.—Every body continues in its state of rest or of uniform motion in a straight line, unless compelled by impressed forces to change that state.
Σελίδα 70 - LAWS OF MOTION. First Law.—Every body continues in its state of rest or of uniform motion in a straight line unless compelled by impressed forces to change that state.
Σελίδα 121 - If three forces acting on a particle be in equilibrium each force is proportional to the sine of the angle between the directions of the other two.
Σελίδα 147 - A pole 12 feet long weighing 25 Ibs. rests with one end against the foot of a wall, and from a point 2 feet from the other end a cord runs horizontally to a point in the wall 8 feet from the ground: find the tension of the cord and the pressure of the lower end of the pole.

Σελίδα 165 - Two uniform cylinders of the same material, one of them 8 inches long and 2 inches in diameter, the other 6 inches long and 3 inches in diameter are joined together end to end so that their axes are in the same straight line. Find the
Σελίδα 205 - A body weighing 54 Ibs. is just set in motion on a rough horizontal plane by a horizontal force of 9 Ibs. If the force be withdrawn and the plane tilted up, at what inclination of the plane to the horizon will the body begin to slide
Σελίδα 65 - A body whose mass is 8 Ibs. is known to be under the action of a •single constant force. It is observed to move from rest and in the first second of its motion to describe a distance of 5 feet: what is the magnitude of the constant force?
Σελίδα 164 - A bar each foot of which weighs 7 Ibs. rests upon a fulcrum distant 3 feet from one extremity : what must be its length that a weight of 71^ Ibs. suspended from that extremity may just be balanced by 20 Ibs. suspended from the other extremity
Σελίδα 191 - A wheel and axle is used to raise a bucket from a well. The radius of the wheel is 15 inches, and while it makes 7 revolutions the bucket, which weighs 30 Ibs., rises 5^
