The velocity ratio of a differential wheel and axle with D as the diameter of effort wheel and d1,and d2 as the diameters of larger and smaller axles respectively, is D/(d₁ + d₂) D/(d₁ - d₂) 2D/(d₁ + d₂) 2D/(d₁ - d₂). Mechanical Engineering Objective type Questions and Answers. K.E. of the fly wheel and shaft combined and w is the final angular velocity of the wheel or of the shaft. 1. Work done due to frictional resistance = f x h where F is the force of force of friction acting tangentially to the shaft. From law of conservation of energy we can write w x h = ½ (w/g) v2 + ½ I (w2 /g) + F x h = 2g (W- F) x h The necessary cords and load hangers are provided and weights are included. An additional load hanger is supplied to enable the simple wheel and axle experiment htm2 to be performed This equipment is part of a range designed to both demonstrate and experimentally confirm basic engineering principles. In differential axle of wheels on simple handle any one undesirable torques as a helical gears, the rear axle will strive to use. The axle and maintenance costs and come in every stage of force b) Experimental study of velocity ratios of simple, compound, Epicyclic and differential gear trains. 2. a) Kinematics of Four Bar, Slider Crank, Crank Rocker, Double crank, Double rocker, Oscillating cylinder Mechanisms. b) Kinematics of single and double universal joints. 3. a) Determination of Mass moment of inertia of Fly wheel and Axle system. wheel and axle. wheel and axle Machine based on the principle that a small force applied to the rim of a wheel will exert a larger force on an object attached to the axle. The mechanical advantage is the ratio of the radius of the wheel to that of the axle. Experiment 7 The Gyroscope "A large acquaintance with particulars often makes us wiser than the possession of abstract formulas, however deep." W. James OBJECTIVES To qualitatively observe some of the motions of a gyroscope. To quantitatively verify a simple motion. THEORY A gyroscope is defined as a rigid rotating object, symmetric about one axis. Lab: BME (ME-107-F) member of a Jib Crane. 11. To study simple screw jack and compound screw jack and determine their efficiency. 12. To find the Mechanical Advantage, Velocity Ratio and Efficiency of a Differential Wheel & Axle. 13. To perform tensile test, plot the stress,-strain diagram and evaluate the tensile properties of a given metallic The wheel and differential axle is secured to a shaft supported on ball bearings. How is a wheel and axle like a lever? In a wheel and axle, the fulcrum is in the center. The outside rim of the wheel is like the handle wheel and axle experiment lab report.
