No I have no new information, I've tried to be as thorough as possible with my post because in the past people have asked for more information. I'm really struggling with understanding this, and I'm not too sure why I am not getting any responses?!

Homework Statement a) For the mechanism shown in figure 1 determine for the angle (45°): i) the velocity (VBO) of the piston relative to the fixed point (O). ii) the angular velocity of AB about point A. iii) the acceleration of point B relative to A. *Note: Link AB is horizontal when angle =...

Thanks, all sorted now... I appreciate your response.

Hi guys, sorry to butt in on this post but I am currently completing this question and I'm struggling with b & c. I've worked through the lesson but cannot see any equations that I can use for the voltage drop across the resistor or the inductor. Would either of you be able to point me in the...

Electrical Science -- LR Time Constant & Voltage Drops 1. An inductor of negligible resistance and an inductance of 0.2 H is connected in series with a 330 Ω resistor to a 12V d.c. supply. Determine: (a) the time constant of the circuit (b) the voltage drop across the inductor after two...

Many thanks for your patience :) Your help is much appreciated!

Thanks, so is 0.2581 mm/s-1 my final answer for vmax or do i need to work out cos(wt+ phi). If so how do i work out t and phi?

Thanks for the reply guys... So, taking v=Aw cos(wt+Ø) I get v = 0.01 x 25.81 cos(25.81t+Ø) v= 0.2581 cos(25.81t+Ø) So multiplying Aw (0.01 x 25.81) gets me 0.2581. What happens with the second part of the equation cos(25.81t+Ø)? That's leaving me a little confused.

Homework Statement A mass of 0.3kg is suspended from a spring of stiffness 200Nm. If the mass is displaced by 10mm from it's equilibrium position and released, for the resulting vibration calculate: a) the frequency of vibration b) the maximum velocity of the mass during the vibration...
