Applied Mechanics and Graphic Statics A square hole is punched out of a circular lamina, the diagonal of the square being the radius of the circle. If ‘r’ is the radius of the circle, the C.G. of the remainder from the corner of the square on the circumference will be [r (π + 0.25)]/(π + 0.5) [r (π - 0.5)]/(π + 0.25) [r (π - 0.25)]/(π - 0.5) [r (π + 0.25)]/(π - 0.5) [r (π + 0.25)]/(π + 0.5) [r (π - 0.5)]/(π + 0.25) [r (π - 0.25)]/(π - 0.5) [r (π + 0.25)]/(π - 0.5) 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) 43832 43959 43898 44079 43832 43959 43898 44079 ANSWER DOWNLOAD EXAMIANS APP
