Theory of Machine When the belt is stationary, it is subjected to some tension known as initial tension. The value of this tension is equal to the Tension in the tight side of the belt Average tension of the tight side and slack side of the belt Sum of the tensions on the tight side and slack side of the belt Tension in the slack side of the belt Tension in the tight side of the belt Average tension of the tight side and slack side of the belt Sum of the tensions on the tight side and slack side of the belt Tension in the slack side of the belt ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The relation l = (2/3).(j + 2) apply only to kinematic chains in which lower pairs are used. This may be used to kinematic chains in which higher pairs are used, but each higher pair may be taken as equivalent to Two lower pairs and one additional link Any one of these Two lower pairs and two additional links One lower pair and two additional links Two lower pairs and one additional link Any one of these Two lower pairs and two additional links One lower pair and two additional links 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
