1. (8 points) A beam carries a distributed load given by w(x) = 250e-0.2 N/m, as shown. Write the total amount or the slice amount in each of parts a-d, in terms of the integration variable. Computations are not required. W x (a) What is the total force on the beam? 5 m (b) What is the moment of a typical slice about the origin, O? (c) What is the moment of a typical slice about the pivot labeled B? (d) What is the moment for this beam about a pivot at an unknown location x = Provide an exact symbolic answer, which will involve a. a in [0,5]?
