    Short Beam Stress Concentration

    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...

    Solving for A and B in a piecewise function

    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.

    Is There a Type of Wood Strong Enough and Affordable for Building Car Frames?

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

    Is There a Type of Wood Strong Enough and Affordable for Building Car Frames?

    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

    Finding the Limit of a Trig Function with Another Trig Function Inside

    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?

    Finding the Limit of a Trig Function with Another Trig Function Inside

    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)

    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
