A 14% Part (b) The vertical center of mass of the sheet will be located: A 14% Part (c) Write a symbolic equation for the total mass of the triangle. A 14% Part (d) Consider a horizontal slice of the triangle that is a distance y from the top of the triangle and has a thickness dy. Write an equation for the area of this slice in terms of the distance y, and the base B and height H of the triangle. A 14% Part (e) Set up an integral to calculate the vertical center of mass of the triangle, assuming it will have the form CJ f(y) where C has all the constants in it and f() is a function of y. What is f())? A 14% Part (f) Integrate to find an equation for the location of the center of mass in the vertical direction. Use the coordinate system specified in the previous parts, with the origin at the top and positive downward. A 14% Part (g) Find the numeric value for the distance between the top of the triangle and the center of mass in cm.(10%) Problem 10: A rod is laid out along the x-axis with one end at the origin and the other end at x = L. The linear density is given by the following: p ( x ) = Pot ( 0 1-2 0 ) (x/ [). where po and py are constant values. @theexpertta.com - tracking id: 5188-75-0E-46-BB99-46140.
