Since the bar i uniform, its center of gravity is at its center The new experiment uses different hooks for hanging the masses from the bar, with mhook 5.0 g.

Explanation / Answer

2. balancing moment(r x F) about hinge point,

(2.5 - 2) x 0.30 x 9.80 - (d x 0.900 x 9.8) = 0

d = 0.15 / 0.9 = 0.167 m

distance from left end = 2 - 0.167 = 1.83 m

3 . data from experiment needed.

figure etc.

3. F = mg = kx

0.030 kg x 9.80 m/s^2 = 8.80 N/m x X

X = 0.0334 m Or 3.34 cm

5. F = kx

16 = k (0.0590)

k = 271.19 N/m
