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 A lead ball with a certain velocity is made to strike a wall, it falls down, but rubber ball of same mass and with same velocity strikes the same wall, it rebounds. Select the correct reason from the following: Both the balls undergo an equal change in momentum None of these The change in momentum suffered by rubber ball is more than the lead ball The change in momentum suffered by rubber ball is less than the lead ball Both the balls undergo an equal change in momentum None of these The change in momentum suffered by rubber ball is more than the lead ball The change in momentum suffered by rubber ball is less than the lead ball 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 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 Meet at one point and their lines of action also lie on the same plane Do not meet at one point, but their lines of action 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 Meet at one point and their lines of action also lie on the same plane ANSWER DOWNLOAD EXAMIANS APP

Engineering Mechanics The principle of transmissibility of forces states that, when a force acts upon a body, its effect is Different at different points on its line of action Minimum, if it acts at the center of gravity of the body Same at every point on its line of action Maximum, if it acts at the center of gravity of the body Different at different points on its line of action Minimum, if it acts at the center of gravity of the body Same at every point on its line of action Maximum, if it acts at the center of gravity of the body ANSWER DOWNLOAD EXAMIANS APP
