Engineering Mechanics A semicircular disc rests on a horizontal surface with its top flat surface horizontal and circular portion touching down. The coefficient of friction between semi circular disc and horizontal surface is µ. This disc is to be pulled by a horizontal force applied at one edge and it always remains horizontal. When the disc is about to start moving, its top horizontal force will Slant down towards direction of pull Remain horizontal None of these Slant up towards direction of pull Slant down towards direction of pull Remain horizontal None of these Slant up towards direction of pull ANSWER DOWNLOAD EXAMIANS APP

Engineering Mechanics The three forces of 100 N, 200 N and 300 N have their lines of action parallel to each other but act in the opposite directions. These forces are known as Coplanar concurrent forces Coplanar non-concurrent forces Like parallel forces Unlike parallel forces Coplanar concurrent forces Coplanar non-concurrent forces Like parallel forces Unlike parallel forces ANSWER DOWNLOAD EXAMIANS APP
Engineering Mechanics The total momentum of a system of masses (i. e. moving bodies) in any one direction remains constant, unless acted upon by an external force in that direction. This statement is called Newton's first law of motion Principle of conservation of energy Principle of conservation of momentum Newton's second law of motion Newton's first law of motion Principle of conservation of energy Principle of conservation of momentum Newton's second law of motion ANSWER DOWNLOAD EXAMIANS APP
