Strengths Lab report Calculating deflection of a statically indeterminate Beam under loading Summary The purpose of this experiment was to investigate the accuracy of theoretical calculation for deflection in beams compared to that of experimental procedure. Our findings showed us that theoretical calculations are an accurate method of approximation and also that deflection directly varies with transverse force applied. Therefore the use of theoretical calculations for engineering design is an accurate and useful and time saving method. We also used load cells to calculate reaction forces and moments. For the calculation of the reaction moment at the support mounted on an arm, the value for the reaction force is multiplied by the distance at which the force is acting.
Newton’s Second Law Lab Purpose: The purpose of this experiment was to determine the relationships between mass, force and acceleration as well as to prove Newton’s second law Hypothesis: It was hypothesized that there would be an inverse relationship between acceleration and mass; as the value of the mass increased the acceleration decreased. As well it is hypothesized that there would be a direct relationship between the net force and acceleration; as the net force increases the acceleration increases as well. Materials & Method: The materials that were required to do the experiment were a metre stick; its purpose was to measure the amount of string that is going to be used to drag the cart. Next equipment needed for the lab was a dynamic cart; it was going to be dragged by the string with a mass on the other end and will find relationships between these two. Also string (about 75cm) was needed in this experiment which would help pull the cart with the help of the masses that were used.
The material changed for each block. Controlled Variables- The controlled variables for this experiment were the distance the block was pulled, the person pulling the block, the person taking the reading and the force metre used. Reliability and fairness: The experiment was reliable to a point, and if were to be done again would need some improvements. During the experiment we made sure we could make it as fair as we could some of the improvements we made were; -Adding
Repeat steps 1-5 for the cord and elastic band 6. Determine the spring constant of each object by graphing F v. Δx for linear springs. If the graph does not appear linear, graph F v. Δx raised to the appropriate constant Part 2: 1. Predict the velocity of the spring when displaced at 0.02, 0.04, 0.06, 0.08, 0.10 meters, using the spring constant derived from part 1 2. Secure the spring to the stand 3.
Hess’s law is one of the most useful relationships in thermochemistry and thermodynamics. Because enthalpy is a state property, any path between a set of reactants and products (under the same initial and final conditions) will produce the same change in enthalpy. If it can be shown that two equations can be combined to give a third (for example, eq 1 + eq. 2 = eq 3), then Hess’s law states that the H’sfor these reactions can be combined similarly to give the H for the combined equation (in this exampleH1 +H2 =H3.) More complicated relationships between equations are handled as follows: if equation x is multiplied by a constant, then Hx is also be multiplied by that constant; if an equation must be reversed, thenHx must be negated.
Simple Harmonic Motion Abstract In this lab experiment we understand the meaning of what a simple harmonic motion is. We also have to understand the origin of periodic motion and to measure the period of an oscillating spring. So in retrospect we are doing this lab experiment to learn and to gain the basic knowledge of a simple harmonic motion. Introduction The definition of a simple harmonic motion is the vibratory motion that occurs when there is a restoring force opposite to and proportional to a displacement. Also a simple harmonic motion is a term that refers to a particular type of oscillatory motion; they are the simplest kind of periodic motion to analyze.
Moments Of Inertia Abstract: Through experimentation the principles of inertia are observed. Inertia is the resistance to changes in state of rotational motion. It depends on the mass of the object being rotated and its shape and size, along with the center of gravity. Initially, the inertia caused by the rotating apparatus must be found. If a string is attached around the circular apparatus with a pulley with weight attached then it would normally fall at the rate of gravity (9.8 m/s^2).
