What is the mechanical disadvantage of a 2nd class lever? When a lever’s load arm is longer than its effort arm, it is said to be at a mechanical disadvantage. It has a low load force to effort ratio. It cannot produce the same load force to effort ratio as a second class lever. How […]
What are point defects in crystals?
What are point defects in crystals? Point defects are lattice defects of zero dimensionality, i.e., they do not possess lattice structure in any dimension. Typical point defects are impurity atoms in a pure metal, vacancies and self-interstitials. What types of defects arise in solids? Point, Line, and Area defects arise in solids. The number and […]
What is the transfer function of Butterworth low pass filter of order 2?
Will soffit vents prevent ice dams?
Will soffit vents prevent ice dams? Houses with good attic ventilation generally do not experience ice dams, and the physics are quite simple: By circulating cool outside air in the attic space (or in the rafter spaces just below the roof deck), the roof surface remains below freezing and cannot melt the snow on the […]
Is Travelling salesman problem NP-complete?
Is Travelling salesman problem NP-complete? In fact, TSP belongs to the class of combinatorial optimization problems known as NP-complete. This means that TSP is classified as NP-hard because it has no “quick” solution and the complexity of calculating the best route will increase when you add more destinations to the problem. What is the difference […]
What are the load factors of dead load and live load?
What are the load factors of dead load and live load? Load combinations For example, in designing a staircase, a dead load factor may be 1.2 times the weight of the structure, and a live load factor may be 1.6 times the maximum expected live load. What is the LRFD method? Load and Resistance Factor […]
What are different Linux distributions?
What are different Linux distributions? This guide highlights 10 Linux distributions and aims to shed light on who their targeted users are. Debian. Gentoo. Ubuntu. Linux Mint. Red Hat Enterprise Linux. CentOS. Fedora. Kali Linux. What are the main two distributions of Linux? There are commercially-backed distributions, such as Fedora (Red Hat), openSUSE (SUSE) and […]
What are the 5 stages of a project?
What are the 5 stages of a project? Developed by the Project Management Institute (PMI), the five phases of project management include conception and initiation, planning, execution, performance/monitoring, and project close. What is Project Scheduling What are the various project scheduling? A project schedule is a timetable that organizes project tasks, activity durations, calendar start […]
How does a cylinder cushion work?
How does a cylinder cushion work? When the cushion spear enters the cushion seal, the air exiting the cylinder is trapped, causing it to compress. This provides a resistance force that decelerates the piston. The cushion seal collapses when air coming through the adjacent port is introduced, allowing for a fast breakaway. What is the […]
How do you find velocity with net force?
How do you find velocity with net force? Net force = force minus body weight. Acceleration = net force ÷ body mass (body weight ÷ the acceleration of gravity [9.81 m/s/s]) Velocity = acceleration × time. What is the difference between force and velocity? A force pushes or pulls on an object, but velocity is […]
