A disabled automobile is pulled by means of two ropes as shown.
The tension in AB is 400 lb and the angle is 20. knowing that the resultant of the resultant of the two forces applied at A is directed along the axis of the automobile, determine by trigonometry;
a) the tension in rope AC.
b) the magnitude of the resultant of the two forces applied at A.
A concrete dam retaining water has a specific weight of concrete of 23.5kn/m3, what is the factor of safety against sliding & overturning and pressure intensity on the base if coefficient of friction is 0.45
Describe in your own words the three strengthening mechanisms i.e., grain size reduction, solid solution strengthening, and strain hardening. Be sure to explain how dislocations are involved in each of the strengthening techniques.
Assuming unit surface area, find the conductive heat loss through the furnace wall and the temperature at the interface of the fire clay and red brick.
A ten-foot high wall will retain a medium dense sand backfill. Determine the Rankine earth pressure diagram and the total active force on the wall.
Consider a cantilever mass-less beam subjected to a concentrated mass at the tip of the beam. Assume, length L, flexural stiffness EI, and mass m.
The volume flow rate of streams into the pipe is given by QA = 0.02t m 3 /s and that of stream B by QB = 0.008t 2 m 3 /s, where t is in seconds. The exit area of the pipe is 0.01m 2 . Find velocity and acceleration of the flow at exit at t = 1s.
