Unformatted text preview: x horizontal and y vertical. (c) Use symmetry to find the y coordinate of the center of mass. What is it? L H 107 To find the xcoordinate: (d) You only need to find the X CoM for one half of the triangle. Explain why. (e) What is the total mass of one of these right triangles, in terms of , L and H ? (f) Write down the equation for y ( x ) for the top right triangle. (g) For this 2d object, the X CoM coordinate is given by an integral over area. Divide the top right triangle into small vertical strips of width dx . Write down an equation for the area, dA , of these strips. (h) Now use your answers to (d) and (f) to solve the integral X CoM = 1 M x dA ....
