Click For Summary
The discussion revolves around a friction-free pulley system lifting a 600-N block. Participants seek clarification on the number of rope strands supporting the weight, the tension in each strand, and how the man's pulling affects the block's movement. Questions also arise about calculating the ideal mechanical advantage and the potential energy increase based on the work done. The need for a diagram is emphasized to aid understanding of the system's mechanics. Overall, the conversation highlights the complexities of force and energy transfer in pulley systems.

1. A 600-N block is lifted by the friction-free pulley system shown.

a. How many strands of rope support the 600-N weight?

b. What is the tension in each strand?

c. What is the tension in the end help by the man?

d. If the man pulls his end down 60 cm, how many cm will the weight rise?

e. What is the ideal mechanical advantage of the pulley system?

f. If the man exerts 60 Joules of work, what will be the increase of PE of the 600-N weight?

okay so for A is it just 1 because its just 1 rope.
and B do we do F*D?
c. the same thing?
idk I am really confused.
please help!

Thread 'Magnitude of buoyant force in fluids of different densities'

The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
