Applied Mechanics and Graphic Statics If a body is lying on a plane whose inclination with the horizontal is less than the angle of friction, then i. a force is required to move the body upwards ii. a force is required to move the body downward iii. the body will not be in equilibrium The correct answer is only (i) both (i) and (iii) both (i) and (ii) only (ii) only (i) both (i) and (iii) both (i) and (ii) only (ii) 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 Friction force acting when the body is in motion Friction force acting when the body is just about to move Ratio of limiting friction and normal reaction Angle between normal reaction and resultant of normal reaction and limiting friction Friction force acting when the body is in motion Friction force acting when the body is just about to move Ratio of limiting friction and normal reaction ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics When a body slides down an inclined surface, the acceleration (f) of the body, is given by f = g sin θ f = g tan θ f = g f = g cos θ f = g sin θ f = g tan θ f = g f = g cos θ ANSWER DOWNLOAD EXAMIANS APP
