We recognize different low-level activities by measuring the user’s continuous weight distribution over the feet with twelve Force Sensing Resistor (FSR) sensors embedded in the insoles of shoes. Using the sensor data as inputs‚ a Support Vector Machine (SVM) classifier identifies up to eighteen mobile activities and a four-directional foot control gesture at approximately 98% accuracy. By understanding user’s present activities and

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

Five Forces This model focuses on the study of the competitive influences or ‘forces’ on a business. When we discuss competitive factors on a firm‚ we usually consider other firms within the same industry selling similar products. [1] and although it is true that other firms in the same industry present competition‚ Porter challenged this over simplified view by considering other forces that will also affect the firms competitive ability . The diagram below highlights the 5 main forces.

Porter’s five competitive forces in business Business is a form of system that exchanged services or goods with money. When we commence a business in Singapore‚ we have to invest in that business with efficient capital. Successful businesses enable us to gain profit and expand our business to a larger size. Therefore‚ there are a few principles that we must comply. The most basic principle would be the Michael Porter’s five competitive forces. Firstly‚ the most major force will be the rivalry among

Title : Shear Force and Bending Moment Objective : To determine the shear force and bending moment when concentrated load‚ symmetrical load and non symmetrical load are applied Introduction The shear force (F) in a beam at any section‚ X‚ is the force transverse to the beam tending cause it to shear across the section. The shear force at any section is taken as positive if the right-hand side tends to slide downwards relative to the left hand portion. The negative force tends to cause

because their velocities will the larger and will need a larger force to go downwards. Air resistance of an object is affected by its mass‚ the total surface area that is exposed by the air resistance‚ and how fast an object is falling. When an object is falling‚ the force diagram will be represented by the force of air of an object pointing upwards and the force of gravity pointing downwards. But the value of the force of air and the force of gravity will not be the same in the beginning of the fall

Research: When we drive our cars‚ motorcycles‚ trucks‚ or any vehicle down the road‚ we are driving them at a certain velocity and direction. All vehicles have a mass to the order of a few hundred pounds. When our vehicles move at a certain speed down the road‚ they create
