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 3/4 5/3 3/5 4/5 3/4 5/3 3/5 4/5 ANSWER DOWNLOAD EXAMIANS APP
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 + 0.25)]/(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) ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics The forces which meet at one point and have their lines of action in different planes are called Intersecting forces Non-coplanar non-current forces Coplanar non-concurrent forces Non-coplanar concurrent forces Intersecting forces Non-coplanar non-current forces Coplanar non-concurrent forces Non-coplanar concurrent forces ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics A stone was thrown vertically upwards from the ground with a velocity of 50 m/sec. After 5 seconds another stone was thrown vertically upwards from the same place. If both the stones strike the ground at the same time, then the velocity with which the second stone was thrown should be (Assume g = 10 m/sec²) 15 m/sec 50 m/sec 25 m/sec 40 m/sec 15 m/sec 50 m/sec 25 m/sec 40 m/sec ANSWER DOWNLOAD EXAMIANS APP
