A Brinell hardness test is performed on a cold-worked aluminum alloy (yield stress = 200 MPa) using a 500 kg load and a standard spherical indenter. The Brinell hardness recorded is approximately 65 kg/mm2. Use GEOMETRICAL METHOD to determine the depth of penetration. Do not use the formular in solving.

Brief Background Penetration hardness is a measure of a materials resistance to indentation. The Rockwell Hardness test is a standard method for characterizing this property of a material. It uses a small indenter, either a hardened ball or diamond cone (Brale), which is pressed into the sample while measuring depth of penetration. There are several scales to select from as indicated in textbook or the chart found in lab. Each scale refers to the type of indenter used and the...

2.59 The Brinell hardness test is used to measure the indentation hardness of materials. It involves penetration of an indenter, in the form of a ball of diameter D (mm), under a load P (kg) as shown in Fig. 2.13a. The Brinell hardness number (BHN) is defined as 2P where A (in mm2) is the spherical surface area and d (in mm) is the diameter of...

I. (SI units) Low-carbon steel with tensile strength-300 MPa, shear strength-220 MPa, and Brinell hardness of 225 HB is turned at a cutting speed-2.5 m/s. Feed-0.20 mm/rev and depth of cut- 3.0 mm. Rake angle - 5° in the direction of chip flow. The resulting chip ratio 0.45. Using the orthogonal model to approximate turning, determine (a) cutting force, (b) feed force, and (c) compute the required power, if mechanical efficiency-80%.

The lever below is constructed of AISI 1050 cold-drawn steel. It
is assumed that bar "DC" is strong enough and hence not part of the
problem. The force "F" fluctuates between 50 and 250 lbf. Calculate
the factor of safety against yielding and fatigue for a desired
reliability of 99.9%. If finite life is predicted, estimate the
number of cycles to failure. Use the Gerber Fatigue Failure
Theory.
