Lab #1 Report
Purpose: The purpose of this lab is to test the tensile strength of a hot rolled and a cold rolled steel coupon, to see the differences between them and how each one could be used in different
situations. List of Materials:
Tinius-Olsen Testing Machine
2 steel coupons, 1 hot rolled and 1 cold rolled.
Digital Caliper
Procedure:
1. Measure the diameter of each coupon with a digital caliper. 2. Attach 1
st
coupon to Tinius-Olsen testing machine run till failure. 3. Repeat with 2
nd
coupon. 4. Data will be stored on file from computer
Results/Analysis/Calculations:
Hot Rolled
Yield Stress (ksi) = 2.067538049 kips
Yield Strain = .08931
Member-end-stiffness K at yield = 10.384 / .08931 in = 116.2692
Modulus of Elasticity = 2.067538049 / .08931 = 23.15012931
Strain at First Hardening = .00701 Ultimate stress (ksi) = 3.02007099 Ultimate strain = .75772
Member-end-stiffness K at ultimate = 15.168 / .75772 in = 20.0179
Strain Ductility = .75772 / .08931 = 8.4842
Modulus of toughness (ksi) = 15.168 * .75772 = 11.4931

Keyon and Jarred performed the following experiment:
A piece of magnesium was placed on a watch glass; the watch glass and magnesium together weighed 2.00 g.
They burned the magnesium and it produced bright light, smoke, heat and a white residue. They then weighed
the white residue on the watch glass. Watch glass with residue weighed 2.25 g. From this information, they
reached separate conclusions:
1
Keyon: The magnesium gained mass, but it was due to some type of problem with their measurements.
Jerrod: The extra mass had to come from the oxygen in the air; burning something always means it combines
with oxygen.
Which student has the best explanation for the gain in weight and why?
Keyon because the experiment should be done several times to make sure they are getting accurate
measurements.
Jerrod is correct because oxygen in the air added mass, by…

Objectives: 1. To determine the density of liquid samples.
2. To form a layer of four given liquid (one on top of the other) according to
the density, from bottom up.
Apparatus : Platform balance,
1 - 25 mL test tube,
1 - 10 mL graduated cylinder,
2 - mL colored water,
2 – mL coconut oil,
4 pcs. Vials.
2 - mL colored alcohol,
2 - mL kerosene
Materials :
Theory:
Density is best described as the compactness of a substance. The more compact is the
substance the in a small space the heavier is the substance. For a less dense substance,
the mass is spread out over a large volume of space. It is a measurement of how heavy of
light is the substance Its mathematical expression is density is the ratio of an object's mass
to its volume. The density of a material…

A sample of zinc metal is allowed to react completely with an excess of hydrochloric acid:
Zn(s) +2 HCl(aq) → ZnCl2(aq) + H2(g)
The hydrogen gas produced is collected over water at 25.0°C. The volume of the gas is 8.55 L, and the
atmospheric pressure is 0.971 atm. Calculate the amount of zinc metal in grams consumed in the
reaction.
(Vapor pressure of water at 25°C = 23.8 mmHg.)
