 A line is recorded as 475.25 m long. It is measured with a 6.5 N tape which is 30.492 m long at 680F under a 10 lb. pull supported at end points. During measurement the temperature is 4.50C and the tape is suspended under a 71 N pull. The line is measured on 3% grade. What is the true horizontal distance? Modulus of elasticity of the tape is 1.93 X 10KPa and cross-sectional area of tape is 0.0284 cm2. Coefficient of expansion of the tape material is 0.0000116 m/0C.


a test of a driver's perception reaction time is being conducted on a special testing track with wet pavement and a driving speed of 50 kph. when the driver is sober, a stop can be made just in time to avoid hitting an object that is visible 40 m. ahead. after a few drinks of san miguel beer, under exactly the same condition, the driver fails to stop in time and strikes the object at a speed of 30 kph. determine the driver's perception-reaction time after he was drinking. assume coefficient of friction is 0.60.

Design a pipe line for village considering following figure. It is

stipulated that one half of the daily supply of 150 litres per capita

per day should be delivered with in eight hours. Take C=45

a)      What must be the size of the pipe to furnish the supply,

if the head available is 12 meters?

b)     If the velocity in this pipe (friction= 0.002 is

ristricted to 1.5 m/sec, find the head loss?



Is it ethical for a company to subcontract equipment and then claim in a proposal that it is produced in house? 

Where is the line drawn between a typical purchased subassembly which goes into a larger product?


a short reinforced concrete column of section 200mm x 22mm is to be reinforced with a 4 numbered steel bars and is required to carry an axial load of 850KN. the stress in the column must not exceed 7N/mm^2 and the stress in the steel must not exceed 150N/mm^2. determine the diameter required for the bars and subsequent stresses occurring in the concrete and the steel under the specified load.

1.   A pump pumps 20-degree water corresponding to 50 liters / s between two tanks. The tanks have a level difference of 50 m (water must be pumped to a higher level). Calculate the pump head if the pipe has a length and diameter of 100 m and 150 mm respectively. Assume that the friction factor is about 0.032. Also appreciate how rough the pipe is.

A butt weld is set on the cross section of an I-shaped beam. There are bending moment M and shear force V at the splicing position, where M=1120 kN·m and V = 374 kN. The beam is made of Q355b steel and semi-automatic weld is used with welding rod E50. The design value of the weld tensile strength fwt is 260 N/mm 2 . Please check whether the strength of the butt weld is safe by calculation.
