Theory of Machine In a four-bar chain it is required to give an oscillatory motion to the follower for a continuous rotation of the crank. For the lengths of 50 mm of crank and 70 mm of the follower, determine theoretical maximum length of coupler. The minimum length of the coupler will be 45 mm Slightly more than 45 mm 95 mm Slightly less than 45 mm 45 mm Slightly more than 45 mm 95 mm Slightly less than 45 mm ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine When the two elements of a pair have a surface contact when relative motion takes place and the surface of one element slides over the surface of the other, the pair formed is known as a Higher pair Lower pair Force-closed pair Self-closed pair Higher pair Lower pair Force-closed pair Self-closed pair ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The sense of Coriolis component 2 ωv is same as that of the relative velocity vector v rotated at 45° in the direction of rotation of the link containing the path 90° in the direction of rotation of the link containing the path 180° in the direction opposite to the rotation of the link containing the path 45° in the direction opposite to the rotation of the link containing the path 45° in the direction of rotation of the link containing the path 90° in the direction of rotation of the link containing the path 180° in the direction opposite to the rotation of the link containing the path 45° in the direction opposite to the rotation of the link containing the path ANSWER DOWNLOAD EXAMIANS APP
