First of all that's not even a beam. the length has to be 10times the height. You can not treat it as a beam. Second, you are not going to have any stress concentration factors on that. Check the tables here...

yes, that's right

Homework Statement ax+b, x>-1 f(x)= bx^2-3, x less than equal to: -1 Homework Equations the limits on both sides The Attempt at a Solution found the limit on both sides of the equation but don't know what to do next.

If it was you in the car you wouldn't be saying that now would you.

Please specify on the Effectiveness of Polymers.

realize that these cars won't absorb as much energy from collisions like a metal does. malleability of metals are critical for this. second imagine being struck by lightning. specific metal is used to separate charges

This is clearly not going to work out

Ohh. I feel so stupid.

it is cos(1- (sin(t)/t)), but what do you do with the (sin(t)/t) in the inside, you can't just assume its 0 because then it does not exist. How are you getting 1-1. Can you explain?

Homework Statement lim t--> 0 cos(1-(sint/t) Homework Equations lim theta-->0 sin(theta)/theta =1 The Attempt at a Solution I usually don't have a problem with these limits, but I've never done 1 with a trig function inside another trig function. So I don't know how to begin this one.

lim t-->0 (sin3tcot5t)/(tcot4t) Homework Statement lim t-->0 (sin3tcot5t)/(tcot4t) I need to find the limit as t approaches 0. Homework Equations lim theta-->0 sin(theta)/(theta) =1 The Attempt at a Solution My attempt is posted, but I'm not sure if its 0 or 12t/5
