Applied Mechanics and Graphic Statics A stone of mass 1 kg is tied to a string of length 1 m and whirled in a horizontal circle at a constant angular speed 5 rad/sec. The tension in the string is, 5 N 10 N 15 N 25 N 5 N 10 N 15 N 25 N ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics A stone was thrown vertically upwards from the ground with a velocity of 50 m/sec. After 5 seconds another stone was thrown vertically upwards from the same place. If both the stones strike the ground at the same time, then the velocity with which the second stone was thrown should be (Assume g = 10 m/sec²) 25 m/sec 15 m/sec 50 m/sec 40 m/sec 25 m/sec 15 m/sec 50 m/sec 40 m/sec ANSWER DOWNLOAD EXAMIANS APP
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 10 m/sec None of these 5 m/sec Zero 10 m/sec None of these ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics If ‘α’ is the angular acceleration of a compound pendulum whose angular displacement is ‘θ’, the frequency of the motion is 2π √(α/θ) 4π √(α/θ) (1/2π) √(α/θ) 2π √(α - θ) 2π √(α/θ) 4π √(α/θ) (1/2π) √(α/θ) 2π √(α - θ) ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics The tension in a cable supporting a lift Is more when the lift is moving downwards Is less when the lift is moving downwards Is less when the lift is moving upwards Remains constant whether its moves downwards or upwards Is more when the lift is moving downwards Is less when the lift is moving downwards Is less when the lift is moving upwards Remains constant whether its moves downwards or upwards ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics The ends of a string weighing w/metre are attached to two points at the same horizontal level. If the central dip is very small, the horizontal tension of the string throughout is wl²/4d wl²/16d wl/4d wl²/8d wl²/4d wl²/16d wl/4d wl²/8d ANSWER DOWNLOAD EXAMIANS APP
