Question.01 Figure TQ3.1 shows two shafts, A and B, arrange in parallel line are geared together through an intermediate parallel shaft, C. Distance of shaft B to shaft X is equal or more than twice the distance of shaft A to X. The wheels connecting A and C have a module of 3, those connecting C and B a module of 4.5. The speed of B is about, but less than 20% that of A. If the pinions have each 30 teeth, find the first three combinations of suitable teeth for the wheels, its actual ratio and its corresponding distance of shaft C to A, and B to D.

You’re using a system of multiple simple machines to move a 1500 N load up a height of 2 meters. You have a wheel barrow which is a combination of a lever and a wheel/axle, and you’ll be using a ramp (inclined plane).a. If you want to apply a maximum effort force of 50 N – what does the actual mechanical advantage of the compound machines need to be? b. The wheel barrow in problem above has the following dimensions Wheel axle radius: 7.5 cmWheel outer radius: 25 cmLoad distance to fulcrum: 55 cm Handle distance to fulcrum: 200 cmWhat is the wheel barrow’s total ideal mechanical advantage? c. Due to a rusty wheel axle, the wheel-barrow in problem above only has an efficiency of 65%. What is the actual mechanical advantage of the wheel barrow?
A simple gear train of 30 and 50 teeth for pinion and gear wheel respectively, is used to drive an electric wheelchair at a velocity that is double the maximum velocity of slip. The pinion has an equal addendum as the gear wheel, a module of 3 mm, and a pressure angle of 14.5°. The wheelchair has a maximum velocity of 5 m/s when its pinion rotates at 800 r.p.m. Calculate: 1.5. The addendum of the gears in mm. 1.6. The contact ratio.
