Question

A tie rod 5 m long is made such that the cross-sectional areas at equal distances are a geometric progression. The area at the smaller end is 10 mm² whilst the area one tenth of the way down the rod is 25 mm². Calculate the area of the cross section at the larger end.

Step 1

- The length of the tie rod is 5 m. - The cross-sectional areas form a geometric progression. - The area at the smaller end (first term, \(a_1\)) is 10 mm². - The area one tenth of the way down the rod (second term, \(a_2\)) is 25 mm². Show more…
