For the following questions answer them individually
A point P moves along the path $$y = x^2 - 4$$. What is the displacement when the point moves from x = 1 to x = 3
The pulley system shown in figure has a mass of 1.5 kg and a radius of gyration of 0.2 m. The angular acceleration of the pulleys, when the suspended masses are released is
A U tube manometer shown in figure is used to measure the gauge pressure of water of density $$\rho_1 = 1000 kg/m^3$$. If the density of manometer liquid $$\rho_2$$ is $$12000 kg/m^3$$ hl = 0.5 m & h2 = 1.0 m, gauge pressure at ‘A’, the centre of tube is (take g = 10 m/s$$^2$$)
A man draws 3 balls from a jug containing 5 whiteballs and 7 black balls. He gets Rs. 20 for each white ball and Rs. 10 for each black ball. What is his expectation?
In dynamic balancing of machines, which of the following is NOT a method of measuring the magnitude andlocation of correction weight for a two plane correction?
The stress produced in a wire of diameter 6 mm, when it is bend around a large cylinder of diameter 2 m can be obtained as (Young’s modulus of both wire and cylinder = 200 GPa, the stress strain curve of the material is given below)
