A COURSE OF Mechanical, Magnetical, Optical, Hydrostatical, AND Pneumatical EXPERIMENTS. To be perform'd by FRANCIS HAUKSBEE; and the Explanatory Lectures read by WILLIAM WHISTON, M. A. MECHANICKS. 1st Day. SIR _ISAAC NEWTON_'s Three Laws of Motion, or Nature, demonstrated by Experiments. That the Velocity of Falling Bodies is as the Times of Falling, and the Lines of Descent in the Duplicate Proportion of those Times. An Instrument to measure the Force of Falling Bodies. Experiments concerning the Sliding, Rolling, and Falling of Bodies. That Bodies will ascend as high, as whence they fall by the last Velocity impress'd, when all Obstacles are removed. That Bodies by a compound Force move in a Diagonal Line. 2d—The Balance and Stilyard, with all their Properties and Uses shewn and explain'd. The Method of estimating the _Momentum_, or Quantity of Motion in any given Body. The general Principle of Mechanicks established upon this Method. Experiments to demonstrate the different Effects of the same Weight of Power acting in different Directions at the same Point of any Engine. The Resolution of Forces into those of other Directions. All the various Kinds of Levers explain'd. 3d—All the Phænomena of Pulleys, both single and in all their possible Combinations explain'd. The Power of the Wheel or Axis in Peritrochio explain'd. The Wedge, with the Method of comparing its Force, deduced from Experiments. The Screw, with the manner of computing its Force. A Compound Engine. 4th—An Experiment of Lifting a Weight by a Chain of Inflated Bladders, with its Application to Muscular Motion. _Galilæo_'s Demonstration concerning the Strength of the Bones, Timber, _&c._ reduced to Experiment. The Method of computing the Force of the Air on the Sails of Windmills, and of Ships; and of Water on Water-Wheels, and on the Rudder of a Ship. Experiments to shew the proportional Advantages of large and small Wheels, in all Sorts of Carriages, as Couches, Waggons, Carts, _&c._ 5th—An Experiment to shew, that the lateral Motion compounded with the perpendicular Projection, does not alter the Line of Ascent or Descent in the projected Body. The most considerable Objections against the Motion of the Earth, answered from this Experiment. That the Line described by a Projectile is a Parabola. The Experiments upon which the Art of Gunnery does depend, most exactly perform'd. 6th—Experiments concerning Pendulums. The Description and chief Properties of the Cycloid, and the Application of Cycloidal Cheeks for regulating the Vibrations of Pendulums. An Experiment to shew the Analogy between the Swings of a Pendulum and the Waves of the Sea. Experiments concerning the Expansion of Metals by Heat.
