How has the use of computers in manufacturing changed the way products are produced? Give three examples.

The flow rate of liquid metal into the downsprue of a mold is 500 cm3/s. The cross-sectional area at the top of the sprue is 8 cm2, and the height of the sprue is 15 cm.

What are the input and output gears of a bike and their movements?

A solid circular steel shaft having an outside diameter of 2.00 in. is subjected to a pure torque of T = 8380 lb-in. The shear modulus of the steel is G = 12,000 ksi. Determine the magnitude of the angle of twist in a 5.00-ft length of shaft.

What is the purpose of a hash function? Choice a To provide integrity Choice b To create a value that cannot be repudiated by its sender Choice c To obfuscate a data segment such that it cannot be deciphered without a key Choice d To preserve a copy

A closed system undergoes a process in which work is done on the system and the heat transfer Q occurs only at temperature Tb. For each case, determine whether the entropy change of the system is positive, negative, zero, or indeterminate.

A scientist who is evaluating an ancient human skeleton for signs of vitamin and nutrient deficiency is conducting:

Which of the following is required in order to make a protected left turn A. A left green arrow B. No oncoming traffic C. A left turn only lane D. A large enough gap

At steady state, a cycle develops a power output of 10 kW for heat addition at a rate of 10 kJ per cycle of operation from a source at 1500 K. Energy is rejected by heat transfer to cooling water at 300 K.

Consider a steady-state experiment in which the observed current due to reduction of Ox to R is 85 mA/cm2.
