1.A 301 stainless steel wire is suspended vertically from itsend. The wire is 400 ft long, diameter .75 inches, specific weight= 489 lb/ cubic foot.
find:
Tensile stress due to the weight of the wire
Max load supported with elastic behavior
Max load supported before failure
2.Compute the suitable equal tangent vertical curve and fullstation elevations for vertical curve that is require to passesthrough a fixed point.
Grades g1 = -2.5 and g2 = +3.7, VPI station is 1+380 withelevation 5210.75. Fixed elevation 5214.00ft at station1+250.00
