Three diagrams relating to the pressuresproduced when beams are suspended horizontally. Sheet 4. (13 X 19.) Three diagrams illustrating the inclinedplane. A weight of 12 units is shown balanced by 3, 4 or6 units according to the inclination of the plane. Sheet 5. (21 x 17.) Two diagrams illustrating statical prin-ciples. (1) Three equal forces act at an angle of 120° on a body. (2) Forces of 14, 8 and 15 act on a body. Sheet 6. A large diagram (34//X4i//) illustrating the principleof moments. Weights are suspended at three points onthe circumference of a disc which is pivotted about acentral horizontal axis. Sheet 7. (20 X 16.) Relates to the parabolic path of projectiles.
