Page 31 - The perpendicular distance between the axis and the line of action of the force. Thus, if the axis MOMENT o
Page 243 - The cycloid is a curve generated by a point on the circumference of a circle which rolls on a straight line tangent to the circle.
Page 93 - Ibs. (Eight inches being the distance from the centre of the shaft to the centre of bearing of the nut on its guides.) Forces causing friction on the bearings are then 120 + 45 + 562.5 = 727.5 Ibs.
Page 328 - ... of importance and should be considered for each case. The ropes commonly used for the transmission of power in factories or mills vary from 3 to 5 inches in circumference. No matter what the diameter of the pulley may be, ropes of 1| inches diameter should not be exceeded for main drives, and ij inches diameter for secondary drives.
Page 6 - BC is the length of the projection of AB on the direction or line of action of the resistance, W. Hence, we have the following statement, which is often useful : — The work done by a force is equal to the product of the force into the length of the projection of the displacement on the line of action or direction of the force.
Page 2 - The unit of force is that force which, acting for one second on a mass of one gramme, gives to it a velocity of one centimetre per second.
