strain-displacement eqns: 6 strain-stress eqns: Plus compatibility equations These equations are called “basic equations”. Difficulties: (1) how to translate an engineering problem to its mechanics model – namely mechanics modelling; (2) difficult to solve for 15 equations simultaneously 4.2 Mechanics Modelling Displacement and Stress boundary condition (B.C.) Let’s look at an example in manufacturing: Cutting tool in a lathe must be sufficiently stiff to avoid vibration and too-tip deflection

sticking to a surface (Coanda effect)‚ and cars being lifted by a small pressure from hand (Pascal’s law)‚ Thermodynamics captured my interest and attention. Subjects such as Heat Transfer‚ Gas Dynamics and Jet Propulsion‚ Thermodynamics‚ and Fluid mechanics further substantiated my interest in the area. Concepts such as Bernoulli’s effect‚ laws of thermodynamics‚ boundary layer and heat engines were equally interesting. Laboratory sessions which allowed me to translate theories to reality further fortified

limitations to care. The continuum of care is one of the concepts that is applied to prevent the limitations within the system. Continuum of care is defined as: A range of services developed and organized to address the variety of needs individuals have as they age. This concept recognizes and considers the availability and extent of short-term and long-term care systems and services in the community and in institutional settings. Included in the continuum of care are residential

Approaches to Decision Making Johanna Ruiz HCA/250 March 29‚ 2013 Robbie Johnson Decision Making Managers are faced with many different types of decision every day on the job and off the job as well. We do make decisions everyday that come naturally to ourselves‚ but when you are placed on a managers position you are not only making a decision that will affect yourself but your employees as well. Employees count on the managers to look out for them and make sure that their best

Understanding Continuum of Care Services Long-term care provides a certain level of medical care that requires the experience of a skilled physician to diagnose and treat multiple chronic conditions that are generally associated with elderly patients. Long-term care provides a variety of services to individuals who suffer from chronic illness or terminal condition‚ including people who live with a disability and are not adequately capable of taking care of themselves over the course of an extended

HOMEWORK 6 EXTRUSION MME 2101 1. A cylindrical billet that is 100 mm long and 50 mm in diameter is reduced by direct (forward) extrusion to a 20 mm diameter. The die angle is 90. the flow curve for the work metal has a strength coefficient of 800 MPa. Determine (a) extrusion ratio‚ (b) true strain (homogeneous deformation)‚ (c) ram pressure‚ and (e) ram force. 2. A billet that is 75 mm long with diameter = 35 mm is direct extruded to a diameter of 20 mm. The extrusion die has a die angle =
