In what situation should a pedestrian give a car right of way? When a pedestrian is crossing a roadway at any point other than within a marked crosswalk or within an unmarked crosswalk at an intersection, he or she must yield the right of way to all vehicles. In other words, a pedestrian does not […]
How do you implement counting semaphores?
How do you implement counting semaphores? Counting Semaphore struct Semaphore. { int value; // processes that can enter in the critical section simultaneously. queue type L; // L contains set of processes which get blocked. } Down (Semaphore S) { SS.value = S.value – 1; //semaphore’s value will get decreased when a new. Can we […]
Do all metals have a slip system?
Do all metals have a slip system? (b) All metals do not have the same slip system. The reason for this is that for most metals, the slip system will consist of the most densely packed crystallographic plane, and within that plane the most closely packed direction. This plane and direction will vary from crystal […]
What does a typical day look like for an electrician?
What does a typical day look like for an electrician? Electricians usually start their days around 7am at the “gang box”, which is a colloquial term in construction for the tool box with all of the materials needed for the project. When the electrician is called in to install the wiring for a building, the […]
When jump starting a car always remember what?
What is Galerkin finite element method?
What is Galerkin finite element method? In mathematics, in the area of numerical analysis, Galerkin methods are a class of methods for converting a continuous operator problem (such as a differential equation) to a discrete problem. the boundary element method for solving integral equations, Krylov subspace methods. What is the weak form of an equation? […]
How do you detect fouling in a heat exchanger?
How do you detect fouling in a heat exchanger? The off-line and on-line methods are build up by dividing the heat exchanger into sections. The states (temperatures) in the sections are represented with physical equations and the Kalman filter is used to estimate the states. Fouling detection is done by monitoring parameters of the model. […]
What makes a control valve become linear equal percentage or quick opening control valve?
What makes a control valve become linear equal percentage or quick opening control valve? Linear valves are used in most applications except heat transfer (temperature control). Non-Linear Valves: If the valve gain rises as the valve opens, its characteristic is called equal percentage (=%) and if its gain drops as it opens, it is called […]
Can ball bearing take axial load?
Can ball bearing take axial load? Yes – radial ball bearings with a retainer (or cage) are designed to take primarily radial loads but have an axial load capacity. Bearings with a greater difference between the bore diameter and outer ring diameter can take larger axial loads as a percentage, sometimes up to 50% of […]
How do you find the coefficient of friction experimentally?
How do you find the coefficient of friction experimentally? You can directly measure the forces involved or you can use some indirect methods, measuring such things as incline of a ramp or time to stop. An experiment to determine the coefficient of friction would be to use some force to push to materials together and […]
