Applied Mechanics and Graphic Statics If ‘v’ and ‘ω’ are linear and angular velocities, the centripetal acceleration of a moving body along the circular path of radius ‘r’, will be ω²/r v²/r r/ω² r/v² ω²/r v²/r r/ω² r/v² ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics A ball is dropped from a height of 2.25 m on a smooth floor and rises to a height of 1.00 m after the bounce. The coefficient of restitution between the ball and the floor is 0.57 0.67 0.44 0.33 0.57 0.67 0.44 0.33 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 - 0.25)]/(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) [r (π + 0.25)]/(π + 0.5) [r (π - 0.5)]/(π + 0.25) ANSWER DOWNLOAD EXAMIANS APP
