Applied Mechanics and Graphic Statics A projectile has maximum range of 40 m on a horizontal plane. If angle of projection is a and the time of flight is 1 second, then sin a must be about (Assume g = 10 m/sec²) 43834 43833 43835 43832 43834 43833 43835 43832 ANSWER DOWNLOAD EXAMIANS APP
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) 43959 43898 44079 43832 43959 43898 44079 43832 ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics It is observed that in a certain sinusoidal oscillation, the amplitude is linearly dependent on the frequency f. If the maximum velocity during the oscillation is V, then V must be proportional to f² 1/f f 1/f² f² 1/f f 1/f² ANSWER DOWNLOAD EXAMIANS APP
