It is the calculation of both energy balances and material balances in a chemical system.

(a)  

A person who weighs 800 N steps onto a scale that is on the floor of an elevator car. If the elevator accelerates upward at a rate of 5 m/s2, what will the scale read (in N)? Round your answer to 2 decimal places.

(a)  

A 2-m long pendulum is pulled aside then released. What is the period of the pendulum (in sec)? Round your answer to 2 decimal places.

(a)  

This occurs where the solid, liquid, and gas transition curves meet and the only condition in which all three phases can coexist and is unique for every material.

(a)  

A Carnot heat engine receives 500KJ of heat per cycle from a high-temperature source at 600 °C and rejects heat a low temperature sink at 40°C. Determine the thermal efficiency (in %) of this Carnot engine. Round your answer to 2 decimal places.

(a)  

How long, in the nearest year, will it take money to triple itself if invested at 8% compounded annually?

(a)  

An earth moving equipment that cost P90,000 will have an estimated salvage value of P18,000 at the end of 8 years. Using double-declining balance method, compute the total depreciation, in pesos, at the end of the 5th year. Round your answer to 2 decimal places.

(a)  

A projectile is fired from the edge of a 150-m cliff with an initial velocity of 180 m/s at an angle of 30° with the horizontal. Neglecting air resistance, find the horizontal distance (in meters) from the gun to the point where the projectile strikes the ground. Round your answer to the nearest whole number.

(a)  

A motorist is traveling on a curved section of highway of radius 2500 ft at the speed of 60 mi/h. The motorist suddenly applies the brakes, causing the automobile to slow down at a constant rate. Knowing that after 8 s the speed has been reduced to 45 mi/h, determine the magnitude of thee acceleration (in ft/s^2) of the automobile immediately after the brakes have been applied. Round your answer to 4 decimal places.

(a)  

It is the value of stress on the stress-strain curve at which the material has deformed plastically; that is, it will no longer return to its original size and shape after removing the load.

(a)  

A steel rod having a cross-sectional area of 300 sq. mm and a length of 150 m is suspended vertically from one end. It supports a tensile load of 20 kN at the lower end. If the unit mass of steel is 7850 kg/m^3 and E = 200x10^3 MN/m^2, find the total elongation of the rod (in mm). Round your answer to 1 decimal place.

(a)  

Determine the maximum shearing stress (in ksi) in a bronze helical spring composed of 20 turns of 1.0 in diameter wire on a mean radius of 4 in when the spring is supporting a load of 500 lb. G = 6x10^6 psi. Round your answer to 2 decimal places.

(a)  

This is the ability of a material to absorb energy when it is deformed elastically and release that energy upon unloading.

(a)  

The ability to resist deformation by abrasion, indentation, or penetration and scratching by harder bodies.

(a)  

This process can be used to measure achievement in Total Quality Management (TQM) system. Also it provides the essential control and measure feedback loop necessary for quality improvement

(a)  

It is the process of attracting potential employees to the company so that the selection process can be carried out.

(a)  

It is an electrical building which houses or encloses electric supply equipment connected to

transmission or distribution lines and the interior of which is accessible, as a rule, only to properly

qualified persons.
