1. A horizontal curve with a radius of 800ft connects the tangents of a two-lane highway with a design superelevation of 0.06 and a coefficient of side friction of 0.14. Lanes are to be 12-feet wide and there is no median. Please calculate: a) What is the speed limit to be posted for a vehicle traversing this curve

Click the game tab at the bottom of the simulation and select level 1. (there is no seesaw balance for this part of the activity.) balance the first equation, and click check to see if you got it right. if you can’t balance it in the first try, you can try again. work through the five equations for level 1. click continue to go on to level 2, and later level 3. each level is more difficult than the one before. keep trying until all the equations are balanced. in one or two sentences, describe how you did in the balancing game. in a few more sentences, explain one strategy you learned for balancing more complex equations.
