Two-lane road has 12-ft lanes. You are asked to design a horizontal curve for this road. The applicable highway design guidelines require the superelevation not to exceed 8%. Due to the cost associated with excavation and vegetation clearing, it was determined that a maximum of 34 ft can be cleared from the centerline of the road toward the inside lane (i. e. toward the center of the curve) to provide for stopping sight distance. Considering these parameters, determine the maximum possible design speed forthis curve.

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.
