How are trusses calculated? Suppose the base of your roof is measured as 40 feet. Now set up the following calculation: Base of triangle = base of roof. After plugging in the numbers, you get 1/40 = 1.06/x (x is the required rafter length). Solving for x, you get x = (40) (1.06) = 42.4 […]

How do you find the length of a cylinder with the radius? First, plug the values of the volume, pi, and radius into the formula for volume of a cylinder. Next, square the radius and multiply the values together. Last, divide each side by 113.04 for the answer, remembering to include the appropriate unit of […]

What test is most applicable to test the convergence or divergence of the series? Ratio Test How do you decide if a series is convergent or divergent? If r < 1, then the series is absolutely convergent. If r > 1, then the series diverges. If r = 1, the ratio test is inconclusive, and […]

Which acoustics room is best? hallway What is the best way to sound proof a room? Cover walls with thick blankets, moving pads, tapestries, or quilts. Virtually any soft material will work, though thicker ones absorb more sound than thinner materials. If you don’t mind adding an industrial look to the room, fasten sound-absorbing panels […]

How do you find the average value of a waveform? The average voltage (VAV) of a sinusoidal waveform is determined by multiplying the peak voltage value by the constant 0.637, which is two divided by pi (π). What is the rms value of a sine wave? The RMS or ROOT MEAN SQUARED value is the […]

How much do mechanics charge to replace sparkplugs? Now you may need to replace several at once, but it still won’t cost very much.
