Applied Mechanics and Graphic Statics A particle moves in a straight line and its position is defined by the equation x = 6 t² - t3 where t is expressed in seconds and ‘x’ in meters. The maximum velocity during the motion is 24 m/sec 6 m/sec 12 m/sec 48 m/sec 24 m/sec 6 m/sec 12 m/sec 48 m/sec ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics If a particle moves with a uniform angular velocity ‘ω’ radians/sec along the circumference of a circle of radius ‘r’, the equation for the velocity of the particle, is v = ω √(y² - r²) y = ω √(y - r) v = ω √(r² - y²) v = ω √(r² + y²) v = ω √(y² - r²) y = ω √(y - r) v = ω √(r² - y²) v = ω √(r² + y²) ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics A vehicle weighing w kg is to run on a circular curve of radius r. If the height of its centre of gravity above the road level is h and the distance between the centres of wheels is 2a, the maximum velocity, in order to avoid over turning, will be 4√(gra/h) ∛(gra/h) gra/h √(gra/h) 4√(gra/h) ∛(gra/h) gra/h √(gra/h) ANSWER DOWNLOAD EXAMIANS APP
