Applied Mechanics and Graphic Statics A string of length 90 cm is fastened to two points ‘A’ and ‘B’ at the same level 60 cm apart. A ring weighing 120 g is slided on the string. A horizontal force ‘P’ is applied to the ring such that it is in equilibrium vertically below ‘B’. The value of ‘P’ is: 40 g 60 g 100 g 80 g 40 g 60 g 100 g 80 g 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 √(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
