Hi, I am trying to use the shooting method to determine the angle of a projectile. However for some values of distance and initial velocity my value for angles get stuck between two values. I want to put a piece of code into my shooting method which can either detect that my while loop has...

I have since solved my problem this is what i used. The recorded velocity was given in volts and the velocity needs to be in m/s, a calibration factor can be determined to change the velocity from volts into m/s. The velocity in volts and in m/s has the same frequency, same sinusoidal wave...

Homework Statement Hi, i have to calculate a calibration factor to change a measurement for velocity in volts from a vibration test rig into a measurement of velocity in m/s. Homework Equations I have data for velocity in volts and i am using the equation v=x'=awcos(wt) to...

minger the report i have been given basically states that the flow rate increases and asks why does it increase and where has the additional flow rate come from.

Hi i have some coursework which has some discussion points i don't quite understand. Describing the experiment. There was an airjet and we have to investiage the velocity distribution at a number of stations along the length to reveal how a uniform jet mixes with its surroundings. The...

Ok i understand the values of the resistors R1 and R2 are 4 and 6 ohms. However i am trying to use the final equation in my first post in a report i am writing. However i do not know where this equation comes from and i need to explain this potentiometer and the values for the R1 and R2 which...

http://i5.photobucket.com/albums/y160/bornstubborn101/circuit3.jpg This is the circuit. Basically i need to calculate the two resistors that would make up the potentiometer at VR1 to give a voltage of 3V. I was going to use VR1 = R2/(R1+R2)*Vs The make: R1= VR1/Vs*(R1+R2)...

I predict a force of 500N will be needed to crush an aluminium can axially. If the cost is too high that is ok, i have chosen this concept to design within a group where we will all be making a design. We will choose the best. I was thinking of a platform with a jack mechanism on it, a...

HI, I am essentially trying to make a car jack style machine except to crush cans rather than to jack up cars. I do not know much about pneumatic systems and how complex they are. The concept will be that a hand operated pneumatic device will crush a can against the housing. I have been...

What a stupid mistake. Thanks.

Hmm... I am not sure if this is right. I am just following a method from a book. But it doesn't have an example like this one. Usually with these problems from the book, you have to use ∫1/x^2+or-a^2 To get the result (1+t2)dt/(3+11t) I made 3+4sinx = 3+ 8t/(1+t^2) Then i add them...

I am trying to solve this integral. Any help would be great. I 5/(3+4sinx) I tried suddinb t=tan x/2 but it gives me a result of: =5 I (1+x^2)/(3+11x) I am not sure what to do with this or if this is the right emthod any help would be great. Thanks Using I for integration sign.
