How do you calculate the pitch diameter of a spur gear? First, you need to define a series of concepts to perform the spur gear calculations: The number of teeth (z). Module (m). Pitch Diameter (d) is the diameter of the pitch circle; its value is: d = m x z. Outside Diameter (de) is […]
How do you find the angular acceleration of a rod?
How do you find the angular acceleration of a rod? 3 Answers Sum of the forces on body equals mass times acceleration at the center of gravity. ∑i→Fi=m→aC. Ax=maxAy−mg=may. Sum of torques about center of gravity equals moment of inertia times angular acceleration. ∑i(→Mi+(→ri−→rC)×→Fi)=IC→α Acceleration of point A must be zero. →aA=→aC+→α×(→rA−→rC)+→ω×(→vA−→vC) How do you […]
What material is helmet made of?
What material is helmet made of? Styrofoam and Koroyd Also known as Expanded Polystyrene (EPS), Styrofoam is one of the most popular materials used for the inner lining in a helmet. It is also commonly known as thermocol and has always been reliable considering its impact-absorbing qualities. What are motorcycle helmets made from? The common […]
What is the difference between engineering strain and true strain in a tensile test?
What is the difference between engineering strain and true strain in a tensile test? Engineering strain is the amount that a material deforms per unit length in a tensile test. Also known as nominal strain. True strain equals the natural log of the quotient of current length over the original length. What is engineering tensile […]
What is the #1 fastest car in the world?
What is the #1 fastest car in the world? #1 SSC Tuatara Using a closed highway near Pahrump, Nevada, the SSC Tuatara managed a one-way run of 330 mph, despite tricky cross-winds. Combined with a previous run of 301 mph, the Tuatara’s two-way average, as certified by Guinness, is 316 mph, making it the fastest […]
How does laminar flow change to turbulent flow?
How does laminar flow change to turbulent flow? When the velocity was low, the dyed layer remained distinct through the entire length of the large tube. When the velocity was increased, the layer broke up at a given point and diffused throughout the fluid’s cross-section. The point at which this happened was the transition point […]
What are the requirements for ventilation?
What are the requirements for ventilation? From the view point of comfortable living & working conditions, the good and efficient ventilation system should meet the following functional requirements: Rate of Supply of Fresh Air. Air movements or Air Changes. Temperature of Air. Humidity. Purity of Air. Why is proper ventilation important? Ventilation helps your home […]
Why strain gauge is used in a bridge configuration?
Why strain gauge is used in a bridge configuration? Strain gauge resistance changes are typically measured in a bridge circuit, to allow for precise measurement of the small resistance changes, and to provide compensation for resistance variations due to temperature. Which strain gauge gives exhibits the highest sensitivity? The single-crystal silicon flexible strain gauge offers […]
How do you find the speed of a transverse wave?
What is metal additive manufacturing?
