Applied Mechanics and Graphic Statics The motion of a particle is described by the relation x = t²- 10t + 30, where x is in meters and t in seconds. The total distance travelled by the particle from t = 0 to t = 10 seconds would be 30 m 60 m 50 m Zero 30 m 60 m 50 m Zero ANSWER DOWNLOAD EXAMIANS APP

Applied Mechanics and Graphic Statics ‘ω’ rad/sec is the angular velocity of a crank whose radius is ‘r’. If it makes θ° with inner dead centre and obliquity of the connecting rod ‘l’ is ‘ϕ’, the velocity v of the piston, is given by the equation ω² (l sin ϕ + r cos φ tan θ) ω (l sin ϕ + r cos ϕ tan θ) ω² (l cos ϕ + r sin ϕ tan θ) ω² (l sin ϕ - r cos θ tan ϕ) ω² (l sin ϕ + r cos φ tan θ) ω (l sin ϕ + r cos ϕ tan θ) ω² (l cos ϕ + r sin ϕ tan θ) ω² (l sin ϕ - r cos θ tan ϕ) ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics Newton’s Law of Motion is: The rate of change of momentum is directly proportional to the impressed force, and takes place in the same direction, in which the force acts To every action, there is always an equal and opposite reaction All listed here Everybody continues in its state of rest or of uniform motion in a straight line, unless it is acted upon by some external force The rate of change of momentum is directly proportional to the impressed force, and takes place in the same direction, in which the force acts To every action, there is always an equal and opposite reaction All listed here Everybody continues in its state of rest or of uniform motion in a straight line, unless it is acted upon by some external force ANSWER DOWNLOAD EXAMIANS APP

Applied Mechanics and Graphic Statics A shell of mass 100 kg travelling with a velocity of 10 m/sec breaks into two equal pieces during an explosion which provides an extra kinetic energy of 20000 Joules. If the pieces continue to move in the same direction as before, then the speed of the faster one must be 50 m/sec 20 m/sec 40 m/sec 30 m/sec 50 m/sec 20 m/sec 40 m/sec 30 m/sec ANSWER DOWNLOAD EXAMIANS APP
