MEASUREMENT OF THE SPRING CONSTANT TWO METHODS COMPARED ABSTRACT A spring is an elastic object, which can be extended and contracted by forces with a constant elastic coefficient. This report assesses two methods for determining the spring constant of a specific spring. One method uses the length that the spring extends and the masses that are attached to the spring. The other method measuring the spring constant is based on the harmonic motion. INTRODUCTION Spring constant is an instinct

the gravitational force F_g causing the particle to fall is opposed by a buoyancy force F_b and a drag force F_d as shown in figure 1. If the particle falls at a constant velocity the forces can be expressed as- F_g= F_d+F_b………(1) We know that gravitational force F_g is given by F_g=mg= ρ_s Vg =(1/6)nD^3 ρ_p g………(2) The buoyance force can be derived as the following with the Archimedes Principle taken onto account F_b=(1/6)nD^3 ρ_L g………(3) We can solve for drag force F_d by combining the

Henry Mintzberg’s Configurations Model of Organisational Forms Name Course Instructor Institution Date Introduction Henry Mintzberg has made significant contributions to strategic management especially in terms of organisational effectiveness. He argues that an effective organization is one that chooses an appropriate configuration, which brings strategy, context and structure into a natural integration. For instance, some organisations

Control Architecture and Algorithms of the Anthropomorphic Biped Robot Bip2000 Christine Azevedo and the BIP team INRIA - 655 Avenue de l’Europe 38330 Montbonnot, France ABSTRACT INRIA [1] and LMS [2] have designed and realized an anthropomorphic legged robot, BIP2000 (fig.1). A planar version achieves walking, and the whole robot is able to keep its balance on one foot while moving. The purpose of this paper is to present the principles and the architecture of the robot control we have used

looking into the center of its hole, they would be able to see her pelvic area. The three weights were positioned so that they were lined up with the center line of the Barbie’s body, so they would not tip over, touch the sensor, or cause an uneven force on the different sides of the doll’s body. If when placing the weights on top of the Barbie, one of the weights fell off and caused an impression in the foam, everything would be taken off the foam and after three minutes passed, the process could

Research In Motion Porter's Five Force Porter’s Five Force Model There are some different approaches available when measuring the profitability in a market, or industry. I choose to use the model by Michael E. Porter, where the profitability potential of an industry, described as the long run return on investment, is reliant on the degree of competition in the selected industry. The five forces that Porter mentions are; threat of entry, supplier power, buyer power, threat of substitutes and

panic in Dhaka and other areas of today's Bangladesh including Rangpur, Dinajpur, Sylhet, Rajshahi, Natore, Mymensing, Dhaka, Chittagong, Comilla, Noakhali, Jamalpur etc. A total number of 1542 persons were killed due to this earthquake out of which five were from Dhaka including two foreigners. Three buildings such as Shaheen Medical Hall, Temple Nazi's Shabagh Math and house occupied by Mrs Stansbury were totally damaged and the government houses for commissioner, collector, judge and civil surgeon

Resolution by Vector Methods OBJECT: To study the composition and resolution of vector quantities. METHOD: Concurrent forces acting on a body are used as examples of vector quantities. These forces are represented by vectors. The resultant and equilibrant of several sets of such known forces are determined by both graphical and analytical methods. These results are tested on a force table as a check on the first condition for the equilibrium of a rigid body. THEORY: Measurable quantities may be classified

each of the industries in which the firm is competing is important because the profitability of various industry differs systematically and predictably over time. The average profitability of an industry is highly influenced by the “5 forces”. • Competitive Force 1: Rivalry among Existing Firms: The average level of profitability is primarily influenced by the nature of rivalry among existing firms in the industry. The competitors of the industry are fighting intensely to grab their market share

equilibrium of a particle. Theory: If the net force on a body is zero then it will not accelerate. If it’s at rest it has static equilibrium. If an unbalanced force acts on a body it will be accelerated. When unbalanced the particle can achieve its equilibrium by having a force that is applied that has an equal magnitude and is in the opposite direction. Procedure: 1. Attach 100 g (1.0 N) at 0 degrees and 100 g (1.0 N) at 270 degrees on the force table. Zero force probe and pull the third string until the
