FE Sample Quiz 1

Determine the modulus of elasticity of a composite material if the strain on the material was 0.09 and the following data are known:

A fisherman tries to stop his boat. The velocity reduces uniformly from 10 m/s to 6 m/s during the first 16 m. What is the total distance traveled by the boat before coming to rest, assuming it continues to decelerate at the same rate?

A test is conducted on a soil sample to determine the hydraulic conductivity of a soil. The sample is a cylindrical container with length 25 cm and circular cross section of diameter 10 cm.

The sample is subjected to a head of 50 cm, and the observed flow rate through the sample is 8 cm3/min. What is the hydraulic conductivity of the soil?

A short post constructed from a hollow circular tube of aluminum supports a compressive load. The inner and outer diameters of the tube are d1 = 3.6 in and d2 = 5.0 in, respectively.

Its length is 40 in. The shortening of the post due to the load is measured as 0.044 in. What is the strain on the post?

A pitot tube is being used to measure the velocity of water flowing through a pipe. A manometer containing mercury is connected to the pitot tube.

It indicates a height of 100 mm. Determine the velocity of the water. (γHg = 133,400 N/m³ )

Determine the modulus of elasticity of a composite material if the strain on the material was 0.06 and the following data are known:

A truck driver tries to stop his truck. The velocity reduces uniformly from 12 m/s to 8 m/s during the first 20 m. What is the total distance traveled by the truck before coming to rest, assuming it continues to decelerate at the same rate?

A test is conducted on a soil sample to determine the hydraulic conductivity of a soil. The sample is a cylindrical container with length 30 cm and circular cross section of diameter 15 cm.

The sample is subjected to a head of 60 cm, and the observed flow rate through the sample is 12 cm3/min. What is the hydraulic conductivity of the soil?

A short post constructed from a hollow circular tube of aluminum supports a compressive load. The inner and outer diameters of the tube are d1 = 5.6 in and d2 = 7.0 in, respectively.

Its length is 60 in. The shortening of the post due to the load is measured as 0.024 in. What is the strain on the post?

What is the probability of rolling a sum of 5 with two dice?
