- 1.A 3-meter chain is hanging straight down the side of a building as shown at the bottom of the page. This chain has a variable density of p= x-3x +10 in kg/m . Acceleration due to gravity is 9.8m/s . We are interested in the work to pull all of the chain to the top of the building. (a) Label the sketch with the location of x = 0. Your choice for the location of zero must be used for the remainder of the problem. (b) Write an expression for F(x,) , the force acting on any small interval of chain. (c) Find the expression for the distance any representative part of the chain must travel (distance in terms of x, ). (The exact expression will depend on your location of zero in (a).) (d) Write the expression for W (x,) , the work to raise any small representative part of the chain. (e) Set up (but do not solve) the Reimann sum that approximates the total work done in lifting all of the chain. (f) Set up and solve the proper definite integral to find the total work done in lifting all of the…arrow_forwardPlease answer in 6 decimal places if applicable and write your solution clearly.
