A uniform meter stick with a mass of 180 g is supported horizontally by two vertical strings, one at the 0-cm mark (with tension T1) and the other at the 80-cm mark (with tension T2). A small pentagonal object of mass = 50g is placed at the 60cm mark. Required:
a. Draw a picture showing all forces acting on the stick (do not forget the weight of the meter stick).
b. Calculate the tensions in the strings at the 0-cm and 80-cm mark by choosing the pivot point at T1.
