b) Determine the speed of the motorcyclist at the instant the acceleration is .
c) Determine the magnitude of the acceleration at the instant the speed of the motorcyclist is .
d) Determine the maximum constant speed of the motorcyclist when the maximum acceleration is .
At an axial load of 23 kN, a 40-mm-wide by 10-mm-thick polyimide polymer bar elongates 2.7 mm while the bar width contracts 0.17 mm. The bar is 240 mm long. At the 23-kN load, the stress in the polymer bar is less than its proportional limit.
The point of intersection of the tangents is located at station (948+67.32). If the design speed of the highway is 60mi/h, determine both the point of tangent and the deflection angles to whole stations for laying out the curve. Select appropriate..
