the depth gauge are common tools. C. Round work is measured by feel with nonprecision tools‚ D. The spring caliper and the firm-joint caliper are nonprecision tools. Answer: Flat surfaces are measured with common tools such as the steel rule and the depth guage. Round work is measured by feel with nonprecision tools such as the spring caliper and the firm-joint caliper. 4. A. Ohm’s law states that the current in an electrical circuit varies directly as the voltage and inversely

Grade 9 Task Term 3 Hydraulics and Pneumatics Section: A 1. a) Good examples of hydraulic systems include automotive brakes‚ and the control systems of large aircraft. Hydraulic systems supply forces somewhere remote from where it is practical to locate large machinery. Hydraulics gives high forces with low losses‚ thanks to the virtual incompressibility of hydraulic fluids. Pneumatics is usually less efficient‚ though simpler since the "reservoir" in the circuit is the atmosphere

open channels such as erosion of soil due to the high velocity flows. In modern day these gates are used in flooding areas in place of barriers‚ dams and in coastal areas in case of tidal wave flooding. Apparatus. Open channel‚ Meter ruler‚ Vernier calliper‚ Sluice gate‚ Slope adjuster‚ Centrifugal pump‚ Electro magnetic flow meter. Procedure. First the dimations of the Channel was measured using the meter ruler. After this the motor was turned ON. The flow of the water level was

------------------------------------------------- PART 1 ------------------------------------------------- History Predecessors The Babylonians sometime in 2000–1600 BC may have invented the quarter square multiplication algorithm to multiply two numbers using only addition‚ subtraction and a table of squares.However it could not be used for division without an additional table of reciprocals. Large tables of quarter squares were used to simplify the accurate multiplication of large numbers

1.0 INTRODUCTION: AISI 304L austenitic stainless steel is widely used as engineering materials due to its high strength and good corrosion resistance properties. However‚ AISI 304L stainless steel undergoes extensive wear and erosion when applied as components in aggressive environments such as petro- chemical and marine atmosphere [1]. Solid particle erosion is defined as the progressive loss of material from a solid surface due to mechanical interaction between the surface and some fluid entrained
