Reason for the spiral curve is a useful easement curve

Expert Solution & Answer
Check Mark

Explanation of Solution

The spiral curve makes an exceptional easement curve because the radius is reduced to infinity of the curve where the tangent of the curve meets.

The easement of the curve is achieved by the spiral curve when the curvature at the junction of the tangent of a circular curve reduces to the sudden changes.

Conclusion:

The easement of the curve is best provided by the spiral curve due to its decrease in radius.

A continuous foundation is shown in Figure 1. If the load eccentricity, e = 0.5 meter. Determine the ultimate load Qult per unit length of the foundation. Use Mayerhof’s effective area method. Given B = 2 meter, Df = 2.0 meter , ϕ = 40 , c’ = 0 kN/m3, γ = 16.5 kN/m3 . Calculate also the Factor of Safety for the shallow foundation.
A simply supported beam is subjected to the end couples (bending is about the strong axis) and the axial load shown in the figure below. These moments and axial load are from service loads and consist of equal parts dead load and live load. Lateral support is provided only at the ends. Neglect the weight of the beam and investigate this member as a beam-column. Use Fy that P40 k and M = 68 ft-k. For W10 × 33: I = 171 in.4; 10 ft and C₁ = 1.0: Mn = 134 ft-kips and Mn/₁ = 89.3 ft-kips; = 50 ksi. Suppose for Lb for Lc - = 10 ft: Pn 330 kips and Pr/c = 220 kips.
