Applied Mechanics and Graphic Statics A car goes round a curve of radius 100 m at 25 m/sec. The angle to the horizontal at which the road must be banked to prevent sideways friction on the car wheels is tan"1 x, where x is (Assume g = 10 m/sec²) 44079 43898 43832 43959 44079 43898 43832 43959 ANSWER DOWNLOAD EXAMIANS APP

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: 100 g 80 g 60 g 40 g 100 g 80 g 60 g 40 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 √(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
