A 30-m steel tape weighs 12.5 g/m and has a crosssection of 0.022 cm^2. It measures correctly whensupported throughout under a tension of 8.0 kg andat a temperature of 20° C. When used in the field, thetape is only supported at its ends, under a pull of 9.0kg, and at an average temperature of 28° C.Determine the correct distance between the zeroand 30-m marks.

A 50 meter steel tape is suspended in the air between a transit and a vertical rod which is placed exactly at the 50 meter mark. The slope of the measured line is 1 degree and 30 minutes. The tension on the tape is 10 kg, and the weight of the tape per unit length is 0.05 kg/m. What normal tension ( N ) is required in order that the effect of sag will be eliminated when the tape is supported at end points only? The standard pull is 10kg. Tape area is 8 mm2. E = 200 GPa. need answers and solutions asap, thank you!

Determine the normal tension required to make a tape exactly 30.0 m between its ends when used in an unsupported mode, if the tape has a cross-sectional area of 0.045cm2 and weighs 0.90 kg. Assume that the tape is exactly 30.0 m when supported throughout its length under a standard pull of 6.0 kg, and its modulus of elasticity is 2.10x106 kg/cm2. Where: PN = normal tension or the pull which will eliminate the effect of sag (kg) W = total weight of tape between supports (kg) A = cross- sectional area of tape (cm2) E = modulus of elasticity of tape material (kg/ cm2) Ps = standard pull for the tape (kg
