Thanks for the clear explanation.

Is it Distance = 0.25 * a * t^2? instead of 0.5? how do we get 0.8m/s^2?

Hi, I'm sizing motor for a linear motion, usually for the time distance graph would be looks like this, however, how does the graph look like if the stroke is very short? Example: velocity is 0.1m/s, acceleration is 1m/s2, moving stroke is 0.5mm, a cycle is within 0.05s the application is to...

Thanks for the responds. Note this is not homework; just bringing up discussion from recent work related task. Should the magnet attraction force works like from gravity force or any force? Meaning the concept is the same like object free falling from higher height would cause higher...

Hi, I'm studying how distance affects the impact of magnet collision. Would like to have some idea before conducting experiment. Imagine 1. holding a magnet at different distance near a fixed metal 2. release the magnet; the magnet attract and collide to the fixed metal Will the distance affect...

Thanks for reply. Will read through the harmonic oscillator. Would prefer reducing the amplitude of the oscillation.

Hi all, I'm studying the compression spring design issue that occurred in a machine design application. As illustrated below, spring is bouncing or oscillating after impact to a stopping surface (1 -> 2 -> 3 -> 4) and eventually stop after few bounces. Ideal case for this application is to...

Hi Dr.D, No, i don't know for both ways and method. Would be great if you could give some advice on these. I was thinking i can estimate the required motor torque by calculating resultant force from Condition2 (which is the highest torque required to reach the position moving from initial...

Hi Dr.D, Compress spring is to always attach the cam follower to the profile of cam. Here i attach a figure (side view) with other element for better understanding on the design. Hope this could help explain the mechanism and question. Thanks.

Hi Dr. D, Thanks for reply. Please see figure below, condition1 shall be initial position, when trigger, motor will rotate direction (1); cam follower will move up following the profile, rotate until condition2, motor will stop (rev can be set; 340degree), then motor rotate in reverse...

If the roller is mounted with bearing, will friction force insignificant and can be ignored?

Hi Jr, Thanks for reply, this is not a homework.

Thanks for reply, It is not a homework. It is for machine designing. The figure is just drafted to show basic mechanism motion.

Hi all, I'm currently designing a linear to linear transform mechanism (wedge cam design). Would like to check how much force required to push/ slide the roller down. To ease calculation, i have include some assumption: F2 = 1kg @ maximum compressed angle = 20degree F1 required = ? and how...

Hi all, I'm currently designing a cam mechanism. Would like to check how much motor rated torque required for the following design of snail cam ? To ease calculation, i have include some assumed factor as below. Two extreme condition (rotation degree) to compare. What is the motor rated...
