A meter stick is made out of aluminum. The scale is accurate at 40°C. Suppose an intrepid student living in Alaska takes the meter stick outside on a very cold winter day to measure the length of a concrete paving stone with dimensions of 10 inches by 10 inches at 40°C. What length will the student measure, if the outside temperature is −46°C? (Give your answer in cm at −46°C. Round your answer to at least two decimal places.)

(a) Suppose a meter stick made of steel and one made of Invar are the same length at 0°C. What is their difference in length at 34.0°C? The coefficient of thermal expansion is 12 x 10-6/°C for steel and 0.9 x 10-6/°C for Invar. mm (b) Repeat the calculation for two 28.0-m-long surveyor's tapes. mm Supporting Materials Physical Constants Submit Answer

What is back-lash error? How can it be avoided in reading instruments based on the Questions micrometer-screw principle? 1s it necessary to measure the increase in length of the rod by the above method, or might a 2 meter stick be used? Approximately what per cent error in the calculated value of the coefficient of linear expansion will be caused by using the length of the rod at room temperature rather than at zero degree C? Does this account for...

A 110-kg steel support rod in a building has a length of 2.0 m at a temperature of 20°C. The rod supports a hanging load of 5,000 kg. (a) Find the work done on the rod as the temperature increases to 37°C. (Assume the average coefficient of linear expansion for steel is 11 x 10-6 (°C) -7.) (b) Find the energy Q added to the rod (assume the specific heat of steel is the same as that for iron, 448...

where λ is the charge density per unit length on the rod and εο is called the permittivity of free space (it is a universal constant with the value 8.854 x 10-12 F/m (farads per metre)) The integral for the electric field can be evaluated exactly using a method called trigonometric substitution with the result AL We won't learn the method of trigonometric substitution in this course; however, you will approximate the value of the integral using methods we introduced...

summarizr the followung info and write them in your own words and break them into different key points. 6.5 Metering Chamber: 6.5.1 The minimum size of the metering box is governed by the metering area required to obtain a representative test area for the specimen (see 7.2) and for maintenance of reasonable test accuracy. For example, for specimens incorporating air spaces or stud spaces, the metering area shall span an integral number of spaces (see 5.5). The depth of...
