1. A car is driving at speed of 80 mph in a circular track with a radius of 1500
ft. The driver applied brake to decelerate the car and after 6 seconds, the speed
decreases to half the original speed. What is the acceleration of the car at the
instant after the brakes have been applied? At ft/s2
A. 9.18 C. 13.4
B. 9.78 D. 14
m= x
m= √5x; (0,5)
m= 2x⁴/x; (0,5)
Note: the slope m = dy/dx
m= 2x - 2; (0,5)
Note: the slope m = dy/dx
loading and span data is as follows
Span AB = 6 m; Full Span UDL = 20 kN/m,
Span BC = 2 m; Full Span UDL = 30 kN/m
Span BC = 6 m; Point Load at C = 15 kN.
is as follows
Full Span UDL = 30 kN/m
Point Load 6m from Support A = 30 kN.
kN is applied the extension measured over a gauge length of 800mm is 0.36 mm and
contraction in diameter is 0.0072 mm. Find Poisson’s ratio and all the elastic constants.
as follows
Full Span UDL = 25 kN/m
Point Load 2m from Support A = 15 kN.
Point Load 6m from Support A = 80 kN.
