AI Thread Summary
To calculate the power of a crane lifting a mass, first determine the work done, which is the product of the weight of the mass and the height lifted. The weight can be calculated by multiplying the mass (500 kg) by the acceleration due to gravity (approximately 9.81 m/s²). Next, divide the total work done by the time taken (15 seconds) to find the power output in watts. The correct answer for this scenario is 9800 W, as it reflects the power required to lift the mass at the specified height and time. Understanding these calculations is essential for accurately determining the power of lifting equipment.

Hey! please can you explain how i do this (not the answer, just an example of how i could fnd the answer to this question)::

Q) A crane can lift a 500kg mass (not weight) to a height of 30m in 15s. How much power would the crane have?

a. 1000 W
b. 2450 W
c. 51 W
d. 9800 W

I'm guessing it would be 51W but not sure since we haven't had any practice @ class...

Thanks everyone!

use the definition of power which is the rate of doing work.

what is the work done by the machine?
what is the time taken?

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanged mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
