Okay. You haven't considered the effect of pressure in the viscous drag. Wont 30 bar pressure create some effect?

http://www.iocl.com/downloads/servo_Transclean_C4_SAE_30.pdf The viscosity of the oil is given in that documentation. It varies with temperature, but i don't know whether it will vary with shear rate. The length of shaft is 120mm (inside fluid column). You can neglect viscous heating because...

I am designing a test rig for my company to test seals. What i have is a shaft spinning in a fluid column that is pressurized to 30 bar. The shaft is spun by a motor and i am currently trying to figure out what motor i should select. The fluid is a C4 SAE 30 Oil, quite viscous actually. My...

a*sin(x)=b*sin(th)+c*sin(y) d+a*cos(x)=b*cos(th)+c*cos(y) Find x and y if all others are constants. I don't get how to solve this system of trigonometric equations in matlab. Please help me out friends. Thanks in advance.

Someone please tell me how to solve these kinda trigonometric equations in matlab! Its urgent and i am stuck for 8-9 hrs now :(

I was making a code for creating four-bar linkage in matlab. So somewhere in between i had to solve the 'freudensteins equation'. I have all the link lengths and two angles of links known, and i have two equations and two variables (the other two angle of links) to find. So here are the...

Oh, thanks for the reply. I would like to get some more feedbacks tho.

I am a sophomore student in Indian Institute Of Technology, doing mechanical engineering (Just introducing myself as this is my first post in this super-mesmerizing website) Well, we haven't yet started any CAD courses in college, and i will have to bunk a few classes tomorrow to attend a...

Can you recommend an ebook to start out with microcontrollers. I am a first year mechanical engineering student and i have no idea about electronics (We only learned electricals in high school). So do i need to learn anything as a prerequisite before i learn microcontrollers?
