Temperature error =
L = length 76ft = 23.165m
a = thermal coefficient of expansion of steel surveyor tape 11.6e 10^-6
T1 = -10 F
T2 = 60 F
Temperature error = 23.165 ( 1+11.6e 10^-6( 60+10))
= 23.216m
error = 23.216 - 23.165
Error =0.051m or 0.167 feet

A steel surveyor's tape is to be used to measure the length of a
line. The tape has a rectangular cross section of 0.05 in. by 0.2
in. and a length of 100 ft when T1=60?F and the tension or
pull on the tape is 21 lb . Determine the true length of the line
if the tape shows the reading to be 463.22 ft when used with a pull
of 38 lb at T2=90?F. The ground on which it...

Design the wood wall formworkfor a 14’ - 10” (14.8 ft) high wall to be placed at the rate of pour of 4 ft per hour, internally vibrated. Assume the mix is made with Type I cement, with no pozzolans or admixtures, and that the temperature of concrete at placing is 75oF. The unit weight of concrete is 150 lbs/ft3with a slump of 3 inches. The forms will have continuing reuse. Assume that deflection is limited to l/360 of the...

Calorimetry is the measurement of heat transfer. Devices that measure the amount of heat released or absorbed during a process are called calorimeters. Coffee cup calorimeter is the simplest calorimeter and is often used to measure the heats of chemical reactions at constant pressure (also called enthalpies). This calorimeter consists of a Styrofoam cup with a plastic lid and a thermometer In today's workshop we will use calorimetry to calculate the standard molar enthalpy of reaction or the enthalpy change...
