Applied Mechanics and Graphic Statics A sphere is resting on two planes BA and BC which are inclined at 45° and 60° respectively with the horizontal. The reaction on the plane BA will be None of these More than that of BC Less than that on BC Equal to that on BC None of these More than that of BC Less than that on BC Equal to that on BC ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics Two balls of masses 3 kg and 6 kg are moving with velocities of 4 m/sec and 1 m/sec respectively, towards each other along the line of their centers. After impact the 3 kg ball comes to rest. This can happen only if the coefficient of restitution between the balls is 2/3 1/3 3/5 1/5 2/3 1/3 3/5 1/5 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 Non-coplanar concurrent forces Non-coplanar non-current forces Intersecting forces Coplanar non-concurrent forces Non-coplanar concurrent forces Non-coplanar non-current forces Intersecting forces Coplanar non-concurrent forces ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics A ladder of weight 'w' rests against a smooth vertical wall, and rests on rough horizontal ground, the coefficient of friction between the ladder and the ground being 1/4. The maximum angle of inclination of the ladder to the vertical, if a man of weight 'w' is to walk to the top of it safely, is tan'1 x, where x is 3 1/3 4 1/4 3 1/3 4 1/4 ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics Kinetic friction may be defined as Angle between normal reaction and resultant of normal reaction and limiting friction Ratio of limiting friction and normal reaction Friction force acting when the body is in motion Friction force acting when the body is just about to move Angle between normal reaction and resultant of normal reaction and limiting friction Ratio of limiting friction and normal reaction Friction force acting when the body is in motion Friction force acting when the body is just about to move 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 1 e*72 e4* e2* 1 e*72 e4* e2* ANSWER DOWNLOAD EXAMIANS APP
