A bar of length L, 50 cm, is attached to a wall and is free torotate. A mass of 3kg is attached to the very end of the bar. Astring runs from the wall to the bar with the conditions listedbelow.
A) What is the tension of the string if the bar is massless?
B) Repeat part A, but the bar now has a linear density of 25 g/m.(x is the distance from the left of the bar, x needs to be inmeters.)
C) You have a massless bar. Hanging from the bar are masses whichare listed below. Where do you place the fulcrum such that thesystem is balanced?
D) Repeat part C, but the bar now has a linear density of 35 g/m.(x is the distance from the left of the bar, x needs to be inmeters.)
