Normal force (N) = 10 kg × 9.8 (acceleration from gravity) = 98 N. Force from kinetic friction (Fr) = 0.5 × 98 N = 49 Newtons. Force from acceleration (Fa) = 10 kg × 1 m/s2 = 10 Newtons. Total tension = Fr + Fa = 49 + 10 = 59 Newtons.

To find out the total amount of yarn you'll use for your project, multiply the number of stitches in your pattern by the number of inches each stitch uses.

The easiest way to spot unbalanced tension is to look for visible knots or loops at the end of each stitch. When the bobbin thread shows on the right side, the needle tension is too tight or the bobbin thread, too loose, as shown at left in the illustration below.

Now find total reading using the equation, TR = MSR+VSR = N+(n x L.C) and apply the zero correction. Take the mean of the different values of the diameter and show that in the result with the proper unit.

The direction of the acceleration is the same as the direction of the net force: 69 degrees. to find the magnitude of the net force, giving you 308 N. Use the magnitude of the force and the mass to find the magnitude of the acceleration: a = F/m = (308 N)/(1,000 kg) = 0.31 m/s2.

The direction of tension is the pull which is given the name tension. Thus, the tension will point away from the mass in the direction of the string/rope. In case of the hanging mass, the string pulls it upwards, so the string/rope exerts an upper force on the mass and the tension will be in the upper side.

The machine typically involves a pulley, a string, and a system of masses. Keys to solving Atwood Machine problems are recognizing that the force transmitted by a string or rope, known as tension, is constant throughout the string, and choosing a consistent direction as positive.

A mass m suspended by a wire of length L is a simple pendulum and undergoes simple harmonic motion for amplitudes less than about 15º. The period of a simple pendulum is T=2π√Lg T = 2 π L g , where L is the length of the string and g is the acceleration due to gravity.

Magnitude is expressed in whole numbers and decimal fractions. For example, a magnitude 5.3 is a moderate earthquake, and a 6.3 is a strong earthquake. Because of the logarithmic basis of the scale, each whole number increase in magnitude represents a tenfold increase in measured amplitude as measured on a seismogram.

Use the magnitude of the force and the mass to find the magnitude of the acceleration: a = F/m = (102 N)/(100 kg) = 1.0 m/s2.
