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 √(r² + y²) v = ω √(r² - y²) y = ω √(y - r) v = ω √(y² - r²) v = ω √(r² + y²) v = ω √(r² - y²) y = ω √(y - r) v = ω √(y² - r²) ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics A shell travelling with a horizontal velocity of 100 m/sec explodes and splits into two parts, one of mass 10 kg and the other of 15 kg. The 15 kg mass drops vertically downward with initial velocity of 100 m/sec and the 10 kg mass begins to travel at an angle to the horizontal of tan”1 x, where x is 43894 43926 43895 43954 43894 43926 43895 43954 ANSWER DOWNLOAD EXAMIANS APP
