equilibrium of forces was investigated through the use of different weights attached to cords which were connected to a central ring‚ while pulleys supported them. This assembly facilitated the force band system to demonstrate that equilibrium will be attaining regardless of disturbances. However‚ due to errors in the experiment‚ the sum of the x and y component did equate to zero as predicted. The graphical solution of the experiment yield a polygon that is completed indicating that all the forces are in

When you hear the word aerodynamics‚ the first thing that comes to mind is airplanes and pilots. There are other applications that apply. For instance‚ the passing of a football. A football that is thrown into the air has inertia. This is the tendency of an object in motion to remain in motion. But because of gravity the ball is pulled down and resistance that slows the ball down. A quarterback through the motions of his and body‚ must balance the forward momentum that he gives the ball‚ fighting

The Effects of Force and Mass on an Object’s Acceleration Abstract: In this lab there were two principals investigated. The first was the relationship between applied force and acceleration. The second was the relationship between mass and acceleration. To study these two relationships‚ my partners and I used a dynamic cart with added mass on it. This cart was then attached to a pulley system on a “frictionless track” where it was pulled by a string bearing mass over the edge

Abstract This purpose of this experiment was to observe the relationship between centripetal acceleration‚ centripetal force‚ and a mass M. In this experiment we used a circular motion apparatus that had a plumb bob attached to a metal shaft (that connected the plumb bob to the vertical shaft) and spring. We found the centripetal force from the spring when it was in circular motion. We hung masses off a pulley system that was attached to the plumb bob until the plumb bob was perpendicular to the

OBJECTIVE The purpose of this module is to investigate hydrostatic forces on a plane surface under partial and full submersion. 2 2. DESCRIPTION The apparatus shown in Figure 1 will be used. It consists of a quarter circle block attached to a cantilevered arm with a rectangular surface on the other end. The pivot point on the arm corresponds to the center of radius of the block.

CE 270 - Final Exam Problem No. 1. (20 points) A rectangular cross-section that is 50 mm wide and 250 mm deep is subjected to shear force of 22 kN‚ axial force (tension) of 16.5 kN and bending moment of 33 kN-m. Calculate and show the stress diagrams in the cross-section. What is the maximum normal stress‚ and where does it occur. What is the maximum shear stress and where does it occur. Problem No. 2 (20 points) Determine the principal stress‚ the maximum in-plane shear stress

Force is required to produce motion in a body. Once it gains motion‚ it will‚ without any further force‚ keep on moving with uniform velocity and zero acceleration only in ideal case where there is no friction force. If friction force was completely removable‚ everything in the universe would then keep on moving without any external force once it was set into motion. But it is a fact that friction can never be completely removed‚ thus the notion of ever uniform velocity is not possible in this real

In this investigation three different variables were tested to determine their effect on the force of friction. All throughout the lab it was important to record the data found to identify how much the three variables affected the force of friction. The purpose of the first part of the lab‚ 4.1 What a Drag!‚ was to measure the force required to pull a block over five different surfaces. The sliding surfaces used in the lab were the tabletop‚ waxed paper‚ paper towel‚ fine sandpaper‚ and coarse sandpaper

Proving the Principles of Force I. Purpose: The purpose of this lab is best understood by the statement of that the net force is described as having a direct proportional relationship to acceleration while having an inverse relation to mass‚ this lab is performed to study the roles of these two variables in the real world and see firsthand how they play a role in net force as well as to test the following hypothesis. II. Hypothesis: If an Atwood machine is used to calculate acceleration on a pulley
