Homework Statement A 0.4m diameter, 50KG, solid pulley wheel is used to derive a conveyor belt system on a production line. The belt is very light and it's mass can be taken as zero. The pulley wheel is accelerated from rest at 2 rads/s^2 for 3 secs, then rotated at a constant velocity for a...

Hi there, I am currently in the middle of studying for an exam in a few weeks time. I would appreciate it if someone could just have a quick look over the following details below and see if I am along the right lines. 1. A solid wheel of mass 15Kg is at the top of a slope 1in4. The slope...

Hi all. I have a Parallel Resonant circuit with a Capacitor in Parallel with an Inductor & Resistor in Series together. Capacitor on the left branch and Inductor & Resistor on the right branch. The question I would like to ask is what effect does the resistor have on the circuit? I...

Flywheel Question?? Hi all I have done the following question: A flywheel , intially rotating at a speed of 600 rev/min, is brought to rest with uniform angular deceleration in 10 seconds. A) How many revolutions does the flywheel make before coming to rest? I used Pheta = (Wo + W)t/2...

Ok taking this into consideration I have done the following. Resistance to motion = 25 tonne x 200 N/tonne = 5000N for truck b = 20 tonne x 200 N/tonne = 4000N for truck c Therefore total resistance to motion is 9000N. Force required to move B & C =...

Sorry still unsure where the distance comes into it. I must be having one of my thick days

and now in english :rolleyes:

Hi all, Another teaser that I have been attempting is the following: A Locomotive (A) pulls two tracks (B) and (C). The masses of A,B & C are 80, 25 and 20 tonne respectively. The train starts from rest and accelerates uniformally to cover 2KM in 8 minutes. Assume the resistance to motion...

A pile driven into ground using a hammer question! Hi all, I have been attempting the following question, could you check my answers /method please :) A pile is driven into the ground by a hammer of mass 500Kg's dropped from a height of 4 meters. The mass of the pile is 40Kg's and the...

Cheers for the speedy response. The question actually says assume there is no air resistance. How is it possible to consider the vertical and horizontal motion of a projectile independently of each other?

Hi all. I am new to the forum. Mechanics is a totally new subject to me and I have a few questions to post over the next few weeks that i would like your feedback on, just to make sure I am along the right lines :) The first won i have done is as follows: 1) How is it possible to consider...
