1. ## What is difference between stress and pressure?

Sir DrD, it seems you are a professor!(always makes students to read,read and read more) that comment made me read my notes again(and some internet articles) to really understand the concept of tensors. i must say i did a foolish mistake. Yes stress is a second order tensor while pressure is zero order tensor. Thank you very much for correcting me.
2. ## What is difference between stress and pressure?

Most of above answers are good and almost explains the difference. only one point to add: 1. pressure is a scalar while stress is a vector. Don't know much, but i will try to answer. First of all some definitions: 1. MoE: It is the ratio of stress to the strain developed. strain is dimensionless and hence the units of MoE are same as that of Stress i.e. N/m2 or Psi. 2.Strength: or i can say maximum strength or Ultimate strength. is the maximum force that a material( in our case steel) can withstand just before fracture. 3.Yield strength: it is the value of stress at which sample starts yielding. i.e. going plastic deformation. as seen from the above definitions all three are not same. e.g. for pure aluminum. the MoE is 10^7 psi, Ultimate strength : 110*10^6 psi and Yield strength: 95*10^6 psi for different steel there is same MoE but different strength as shown in the image.
3. ## What is difference between underactuated motion and fully actuated motion ?

state difference between under actuated and fully actuated motion. explain with the example?
4. ## We want to start a new Job section for Mechanical engineers

I am a student and many on this forum are students like me. the idea of opening a job portal is very nice. and can you also make a portal for internship and training programs offered by industries and institutes. our institute have various research projects that are open to every one. see if you can add such section.
5. ## What do you test on Universal testing machine?

Sure! in second year of my course
6. ## Video lectures on Robotics

hey, I tried looking up for the above link but it say "Item not found". and I was not able to copy the links from second post. it would be very helpful if you can post them again as hyperlink.
7. ## What do you test on Universal testing machine?

Just to add few things: With UTM we calculate the Yield strength(upper and lower), Proportionality limit, Ultimate tensile/compression strength, modulus of elasticity etc. The name universal signifies its versatility.
8. ## What is an equivalent length of column ?

when deriving the above formula we considered a case in which both the joints are pinned at ends. rather than deriving the formula for all other cases. we took some most used cases and generalized the formula using effective length. there is no formal definition for effective length but can be defined as. The length of an imaginary section of the column which is equivalent to a pinned-pinned column with same cross-section and material property. this is better explained in the picture itself.
9. ## What is meant by quality of steam?

Steam quality is the proportion of saturated steam (vapor) in a saturated condensate (liquid)/ steam (vapor) mixture. A steam quality of 0 indicates 100 % liquid, (condensate) while a steam quality of 100 indicates 100 % steam.
