17 cm 0.45 kg 76 cm 0.65 kg A 50 g meter stick is balanced at its midpoint (50-cm). Then a 0.45 kg and a 0.65 kg mass are suspended, using light strings, from the 17 cm and 76 cm points as shown above. a. What are the force(s) acting on the meter stick at the pivot point location (50-cm)? What are their magnitudes? Submission type: Submit entries below as answer to receive credit Save entries below (not submitted for credit yet) Rich formatting >> The forces acting on the meter stick at the pivot point are the weight forces on the first block (4.41N), the second block (6.37N), and the stick itself (0.49N). Finally, there is also the normal force from the pivot onto the stick (11.27N). Submit Answer Your submission has been recorded.
