I have a CAD model of a car chassis and would like to place loads on the beams on which the suspension would be acting on in order to get an idea of the stress involved in the chassis and the beams that are most likely to fail. I have ProEngineer and Autodesk Simulation Multiphysics.

Is there a tutorial out there that can guide me on how to take the ProE .asm file and place loads to gather data?

I'm teaching a 10th grade (year 11) class on additive manufacturing and I'm wanting to give the students a list of vocabulary relating to AM. I've had trouble finding a decent list anywhere online and I don't want to miss anything too important. A link to a list of terminology would be useful, thanks!

Could I have a link to saltwater resistant rivet that will withstand a bearing stress of 350MPa and that is >5mm length + 4mm diameter

Thank you!

I am designing a pin joint to support

45.5MPa shear stress

100MPa bearing stress

What materials should I be looking at?

I will be making the pins 1.4cm diameter and 1cm length.

I have the following code:

%Finding poles

poles=roots(den);

p1=real(poles);

p2=imag(poles);

a=1/(abs(p1)); b=1/(abs(p2)); c=pi/(k*wn);

dt=0.01*min(a, b, c);

tmax=10*max(a, b, c);

but i get an error saying

Error using min

MIN with two matrices to compare and a working dimension is not supported.

Error in m286_wk5_data_200821393 (line 19)

dt=0.01*min(a, b, c);

how do I fix this?

thank you

If possible also with touchscreen.

And theres another app that I forgot the name of which allows you to control your MacBook from your iPad whilst streaming the display onto the iPad screen. Anybody know the name for that?

....I need to place in the top 200 with most votes on this website. Please help me turn my dream into a reality!!!

Thank you!

An aluminium cylindrical strain gauge load call is to be specified to

measure a force of 40 kN. The maximum stress in the metal is to be 20 MPa, the modulus of

elasticity is 65 GPa and Poisson’s ratio is 0.33. If it is instrumented with four active strain

gauges (two axial and two transverse) with S = 2.1, R = 350 Ω, and the power supply is 10 V,

what will be the output at maximum load?

A strip of cast iron is 20 cm long and has a cross-section of 3 cm by 0.4 cm. The strip is

subjected to an axial load of 450 kg. Strain gauges are attached to the iron, one in the axial

direction and one in the transverse direction. The axial gauge indicates a strain of 1100 με

and the transverse gauge indicates a strain of -300 με. Estimate the modulus of elasticity and

Poisson’s ratio for this material.

I have no clue how to apply the strains to the question after finding stress.

The following question is about the tropical regions of the Mekong Delta:

After the rice is picked by individual farmers (not commercial), where is it transported to in order for it to get distributed?

I am asking for a specific location in Vietnam.

Again, I am wondering about local farmers who have to then transport it by boat, not mass production in business-owned fields.

With explanation please

well my IB HL data booklet says deltax(deltap)>h/4pi

but every other online resource (almost) says >h/2pi

So which is it?

Why are there 2 different values?

Monday and tuesday i had a massage

nothing hurt before the massage

wednesday i had a workout...full body like usual...nothing out of the ordinary. usually i can deadlift 165kg 3 reps

this time i couldnt lift 95kg more than 5 times

since then my lower back kills.

is it permanent?

how do i fix it?

Ive been bodybuilding for 2-3 years now and looking at blood tests before taking supplements i already had high bilirubin (13.9 mg/L) and creatine levels. about 2 years later I took the test again. been taking supplements for about a month. i have a bilirubin of 18.45 mg/L. could the creatine/whey be causing this and if yes is it bad? how do I lower them? Is it normal for a body builder/athlete to have such levels?
