1. The middle ordinate of a simple curve is 2m and its long chord is 30m, determine its radius.
2. The angle of intersection of a circular curve is 45°30' and its radius is 198.17m P.C. is at Station 0+700.
a. Compute the right angle offset from Sta. 0 + 736.58 on the curve to tangent through P.C.
b. Compute the deflection angle of Sta. 0+736.58 from the tangent through P.C.
c. Determine the degree of the curve. Use chord basis and assume 20m length of chain.
A steady force T is applied at an angle θ to a cord wrapped around the groove as shown. If T = 30N, θ = 0, μs = 0.10, and μk = 0.08, determine the angular acceleration of the disk, the acceleration α of its mass center G, and the friction forc..
