Answer» ation of line of action is 2y - x = 0.Explanation:The MAGNITUDES of forces are 1N and 2N.They act along x = 0 (y-axis) and y = 0 (x-axis). (REFER the FIGURE).So, their resultant R would be passed through origin along the line y = mx. This will be line of action.Also, we can understand the coordinate of R will be (2,1) (refer the figure).SINCE, their resultant would be passed through y = mxHere, m is the slope of line y = mx. R(2,1) will satisfy the equation y = mx. Because, R lies on it.Therefore; put x = 2 and y = 1 in y = mx Hence; the equation of line of action will be represented by equation; 2y - x = 0Thus, the equation of line of action is 2y - x = 0. |
