1. A0.5 kg uniform meter stick is hinged at 0.5 cm from one end and held horizontally by a force T applied at an angle of 30° with the horizontal as shown in figure 1. a. If T is applied at the end of the meter stick as shown, what is the magnitude of T and what is the force F exerted at the pivot on the meter stick? T figure 1 30° b. If the force Tis applied in the same direction but at 60 cm from the pivot, what are T and F? c. How do T and F from part (b) change if, as shown in figure 2, a mass of 1 kg is suspended 35 cm from the left end of the meter stick?
