What wood joint is the weakest? Butt Joint What is the strongest joining method for wood? Mortise and Tenon Joint The mortise and tenon is a classic wood joinery method. These joints have been used since the early times of woodworking, and are still among the strongest and most elegant methods for joining wood. How […]

What are over damped critically and under damped systems? An overdamped system moves slowly toward equilibrium. An underdamped system moves quickly to equilibrium, but will oscillate about the equilibrium point as it does so. A critically damped system moves as quickly as possible toward equilibrium without oscillating about the equilibrium. What is the effect of […]

How is Froude number calculated? It is generally expressed as Fr = v/(gd)1/2, in which d is depth of flow, g is the gravitational acceleration (equal to the specific weight of the water divided by its density, in fluid mechanics), v is the celerity of a small surface (or gravity) wave, and Fr is the […]

What to add to soup to make it taste better? The best part, most are already in your fridge or pantry. Lemon Juice. Acidity in a soup can really make a difference because it adds a high back-note. Wine. Wine is the perfect liquid to unstick the brown stuff from the bottom of your pan. […]

How do you calculate the natural frequency of a beam? The formula used for cantilever beam natural frequency calculations is: $${ f }_{ n }=\frac { { K }_{ n } }{ 2\pi } \sqrt { \frac { EIg }{ w{ l }^{ 4 } } } $$. E in the formula is modulus of […]

Does temperature remain constant in an adiabatic process? An adiabatic process is a thermodynamic process during which no energy is transferred as heat across the boundaries of the system. As there is no exchange of heat with surroundings, so total heat of the system remains constant. What stays constant in an adiabatic process? Remember adiabatic […]

How do you find the IMA of a fixed pulley? In general, the IMA = the resistance force, Fr, divided by the effort force, Fe. IMA also equals the distance over which the effort is applied, de, divided by the distance the load travels, dr. What is the mechanical advantage of a fixed pulley? Pulleys […]

What is the motor in a car? The engine is the heart of your car. It is a complex machine built to convert heat from burning gas into the force that turns the road wheels. It consists of two basic parts: the lower, heavier section is the cylinder block, a casing for the engine’s main […]

How are standard sectional switch device boxes mounted? How are standard sectional switch (device) boxes mounted? NEC 314.20 states that boxes must be mounted so that they will be set back not more than 1/4in. (6mm) in noncombustible walls or ceilings and flush when installed in combustible. How high above the finished floor in the […]
