Applied Mechanics and Graphic Statics One end of an elastic string of natural length ‘l’ and modulus ‘X’ is kept fixed while to the other end is attached a particle of mass m which is hanging freely under gravity. The particle is pulled down vertically through a distance ‘x’, held at rest and then released.The motion is A rectilinear motion with constant speed A damped oscillatory motion None of these A simple harmonic motion A rectilinear motion with constant speed A damped oscillatory motion None of these A simple harmonic motion ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics A rope is wrapped twice around a rough pole with a coefficient of friction ‘A . It is subjected to a force Fj at one end and a gradually increasing force F2 is applied at the other end till the rope just starts slip-ping. At this instant the ratio of F2 to Fi is e4* 1 e*72 e2* e4* 1 e*72 e2* ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics On a ladder resisting on a smooth ground and leaning against a rough vertical wall, the force of friction acts Upwards at its upper end Away from the wall at its upper end Downwards at its upper end Towards the wall at its upper end Upwards at its upper end Away from the wall at its upper end Downwards at its upper end Towards the wall at its upper end ANSWER DOWNLOAD EXAMIANS APP
