Webb8 okt. 2024 · Firstly, mechanical spring work is a type of mechanical work which you calculate as the difference between the first and second squeezing distances of a mechanical spring. You can release a portion of energy to make work such as by pushing a body or box forward. And also, calculate the work with the formulation below; Webb1 nov. 2016 · Analysis of Frames using the Force Method. Step 1: Calculate the degree of static indeterminacy of the structure. D = (3M + R) – 3N. Where; M = Number of members; R = Number of support reactions; N = Number of nodes. In this case; D = (3 x 3 + 5) – (3 x 4) = 2. Therefore the structure is statically indeterminate to the 2nd order.
