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 […]

How do you find the voltage across a capacitor in series? Two or more capacitors in series will always have equal amounts of coulomb charge across their plates. As the charge, ( Q ) is equal and constant, the voltage drop across the capacitor is determined by the value of the capacitor only as V […]

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? 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? Second Order Butterworth Filter Transfer Function: 2.78. At the cut off frequency fH, the gain is 0,707 Af i,e. 3 dB down from its 0 Hz level. After, fH ( f > fH ) the gain rolls off at a frequency rate […]

What is the most common cause of scored brake drums? Scored Brake Drums This condition is caused by interference between the hub and drum mounting surface during installation as a result of using the wrong drum for the application or improperly cleaning the hub piloting surface prior to drum installation. What causes brake drums to […]

Why FET is called field effect transistor? Field effect transistors (FETs) work on a pricipal that uses the field produced by the gate in a way that makes the channel conduct more or less. The FET was named such because the of how the static field, as apposed to current, plays a central role in […]

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? 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? 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 […]
