Homework Statement The bars in the truss each have a cross sectional area of 1.2in^2. If the maximum axial stress in any bar is not to exceed 25ksi, determine the maximum magnitude of P of the loads that can be applied to the truss. Determine the elongation of each member. E=29,000 ksi...

Homework Statement "A friend asks you how much pressure is in your car tires. You know that the tire manufacturer recommends 30psi, but it's been a while since you've checked. You can't find a tire gauge in the car, but you do find the owner's manual and a ruler. From the owner's manual you...

Is this equation a redox reaction? If it is how do I recognize it? I can't seem to complete this. If it is a redox equation, what are the two half reactions because there are three reactants? Cl^{-}~+~Ag[(NH_{3})_{2}]^{+}~+~H^{+}==>~?? Thanks.

Homework Statement A basketball player who is 2.00[m] tall is standing on the floor 10.0 [m] from the basket, as in the figure. If he shoots the ball at 40.0degrees angle with the horizontal, at what initial speed must he throw so that it goes through the hoob without striking the backboard...

Thanks for the help. It was stupid of me to think of ax instead of just thinking g the whole time. This clarified things a bunch, thanks!

Homework Statement A physics student on PLanet Exidor throws a ball, and it follows hte parabolic trajectgory shown in the figure. The ball's position is shown at 1.00[s] intervals until t=3.00[s]. At t=1.00[s], the ball's velocity is v=(2.00i + 2.00j)[m/s]. a. Determine the ball's...
