ABSTRACT

As stated in paragraph 8.1, the Centre of Gravity is the point where the entire weight of the object appears to be concentrated. This is the principle that underlies the method of computation in Example 8.1. It also provides a convenient experimental method for finding the C.G. If the body is suspended from any point, it will rotate until the C.G. is vertically beneath the point of support. (Can you explain why this is so?) By suspending the body several times from different points, and drawing the vertical through each point of support, the C.G. may be found. https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781315272559/5757e623-6aa8-45f1-98cb-a952b7299e79/content/page114_1.tif" xmlns:xlink="https://www.w3.org/1999/xlink"/>
