Engineering Mechanics The resultant of two forces P and Q (such that P > Q) acting along the same straight line, but in opposite direction, is given by Q / P P + Q P / Q P - Q Q / P P + Q P / Q P - Q ANSWER DOWNLOAD EXAMIANS APP
Engineering Mechanics The law of the machine is (where P = Effort applied to lift the load, m = A constant which is equal to the slope of the line, W = Load lifted, and C = Another constant which represents the machine friction.) P = mW + C P = C - mW P = mW - C P = m/W + C P = mW + C P = C - mW P = mW - C P = m/W + C ANSWER DOWNLOAD EXAMIANS APP
Engineering Mechanics The angle between two forces when the resultant is maximum and minimum respectively are 180° and 0° 90° and 180° 0° and 180° 90° and 0° 180° and 0° 90° and 180° 0° and 180° 90° and 0° ANSWER DOWNLOAD EXAMIANS APP

Engineering Mechanics The forces, which meet at one point, but their lines of action do not lie in a plane, are called Non-coplanar concurrent forces Coplanar non-concurrent forces Non-coplanar non-concurrent forces Intersecting forces Non-coplanar concurrent forces Coplanar non-concurrent forces Non-coplanar non-concurrent forces Intersecting forces ANSWER DOWNLOAD EXAMIANS APP
Engineering Mechanics Coplanar concurrent forces are those forces which Do not meet at one point, but their lines of action lie on the same plane Meet at one point and their lines of action also lie on the same plane Do not meet at one point and their lines of action do not lie on the same plane Meet at one point, but their lines of action do not lie on the same plane Do not meet at one point, but their lines of action lie on the same plane Meet at one point and their lines of action also lie on the same plane Do not meet at one point and their lines of action do not lie on the same plane Meet at one point, but their lines of action do not lie on the same plane ANSWER DOWNLOAD EXAMIANS APP
