Chapter 9, Problem 61P

locate the centroid of the area under the curve x = ky3 from x = 0 to x = a

Locate y of centroid of the area and find moment of intertia ly y= asin pi x/L.

A cross section of a beam is bounded by the x-axis and the positive values of the function y = 4 – x. Find the coordinates of the centroid of the cross section.

determine the centroid of the surface given in the figure and its static moment against the X and Y axes of the coordinate system 3m- 5m y 1m Figura 1 5m 2m X

Locate the centroid of the cross section below Hint: Cut the cross section into a rectangular shapes and determine thecentroids of the each rectangle. Use the formula AT (X) = A1 (x1) + A2(x2) + A3 (x3) to solve for x and AT (y)= A1(y1) + A2 (y2) + A3y3t o solve for Y. AT = A1+A2 + A3
