Strength of Materials A semi-circular disc rests on a horizontal surface with its top flat surface horizontal and circular portion touching down. The coefficient of friction between semi-cricular disc and horizontal surface is i. 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 remain horizontal slant up towards direction of pull slant down towards direction of pull unpredictable remain horizontal slant up towards direction of pull slant down towards direction of pull unpredictable ANSWER DOWNLOAD EXAMIANS APP
Strength of Materials According to principle of transmissibility of forces, the effect of a force upon a body is Maximum when it acts at the center of gravity of a body The same at every point in its line of action Different at different points in its line of action Minimum when it acts at the C.G. of the body Maximum when it acts at the center of gravity of a body The same at every point in its line of action Different at different points in its line of action Minimum when it acts at the C.G. of the body ANSWER DOWNLOAD EXAMIANS APP
Strength of Materials Least force required to draw a body up the inclined plane is W sin (plane inclination + friction angle) applied in the direction vertically horizontally along the plane at an angle equal to the angle of friction to the inclined plane vertically horizontally along the plane at an angle equal to the angle of friction to the inclined plane ANSWER DOWNLOAD EXAMIANS APP
