Applied Mechanics and Graphic Statics Ball ‘A’ of mass 250 g moving on a smooth horizontal table with a velocity of 10 m/s hits an identical stationary ball ‘B’ on the table. If the impact is perfectly elastic, the velocity of the ball ‘B’ just after impact would be 5 m/sec Zero None of these 10 m/sec 5 m/sec Zero None of these 10 m/sec ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics If the angle of projection is double the angle of inclination (α) of the plane on which particle is projected, the ratio of times of flight up the inclined plane and down the inclined plane, will be ½ sin α 2 cos α ½ cos α ½ tan α ½ sin α 2 cos α ½ cos α ½ tan α ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics A square hole is punched out of a circular lamina, the diagonal of the square being the radius of the circle. If ‘r’ is the radius of the circle, the C.G. of the remainder from the corner of the square on the circumference will be [r (π + 0.25)]/(π - 0.5) [r (π - 0.5)]/(π + 0.25) [r (π - 0.25)]/(π - 0.5) [r (π + 0.25)]/(π + 0.5) [r (π + 0.25)]/(π - 0.5) [r (π - 0.5)]/(π + 0.25) [r (π - 0.25)]/(π - 0.5) [r (π + 0.25)]/(π + 0.5) ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics A body is dropped from a height of 100 m and at the same time another body is projected vertically upward with a velocity of 10 m/sec.
