Applied Mechanics and Graphic Statics A body A of mass 6.6 kg which is lying on a horizontal platform 4.5 m from its edge is connected to the end of a light string whose other end is supporting a body of mass 3.2 kg as shown in below figure. If the friction between the platform and the body A is 1/3, the acceleration is 0.5 m/sec² 1.25 m/sec² 0.75 m/sec² 1.00 m/sec² 0.5 m/sec² 1.25 m/sec² 0.75 m/sec² 1.00 m/sec² 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 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) v = ω √(y² - r²) ANSWER DOWNLOAD EXAMIANS APP
