Homework Statement Explain the concept of derivative and its role in mechanical engineering. Explain the concept of integral and its role in mechanical engineering. How should I answer this questions? Can anyone give me some guideline to answer this question? Thanks in advance.

Yes i did...Is my way of doing correct?

Homework Statement In the attachment Homework Equations The Attempt at a Solution I have been solving this question for quite some time but I can't get the answer yet. I offset all the forces to point C and I get the following values: Moment at y-axis, M(y) = 10Nm Moment at...

Homework Statement A vessel of capacity 3m^3 contains air at a pressure of 1.5 bar and a temperature of 25 celcius. Additional air is now pumped into the system until the pressure rises to 30 bar and temperature rises to 60 celcius. Determine the mass of air and express the quantity as a...

What strength do you mean?

Besides by increasing the fracture toughness of certain materials to reduce the brittleness, is there any other way to do it?

Does brittle material has any good side? Does it hold any advantage than others materials?

I am currently doing an assignment based on brittleness. But it seems like there is not much information I can get by google it..Can anyone help me to find more information about this topic? Thanks in advance..:smile:

One more thing have to be confirmed. For uniformly distributed load, Mx = (Ay)(x) - (wx^2)/2 (where x is the distance from staring point to x, Ay is the reaction force at the starting point and w is the force per unit length and Mx is the bending moment) Let say if there is a constant moment...

Is the given answer correct or false?

Does it mean when there is a constant moment at point b, then we should either add or substract that value of constant moment in that point (either draw a straight line goes up or goes down)?

After separate the diagram to several parts, I can only find the value of A-y-component = 175N by taking moment at C. But how come I can't get that value if I use F-y component = 0??

Can anyone draw me a correct Bending moment diagram and shear force diagram for this beam? i have drawn the shear force diagram for this case but I do not know how to draw the bending moment disgram for this case because this question involve a constant moment. Normally the rule for bending...

I have two different ways to solve this question. The first method is using the method taught in textbook: Draw the parallelogram and bend F to a direction which is perpendicular to the resultant force, and use sine rule to find F. The second method I use is by assuming the direction of the...

tan (x/2) substitution? How?
