The sides of the rectangle are 18 cm and 26 cm. . The torque at the shaft can be calculated by modifying (3) to. The formula for circumference is the diameter times pi. The angular acceleration of the wheel is? Select the rim size from the drop down box or manually enter the rim diameter size (not the width). If the two wheels are front and rear wheel, both distances should be equal. circumference = 2×pie×r. C=pi times diameter Now we can plug in the numbers: C=3.14*66 Do the calculations C=207.24 cm for one rotation of the tire. The radius of the circular field is equal to the side of a square field. Since we are given the diameter of the wheel, we use the circumference formula C = pd We are given that the diameter is 66 cm, so we substitute 66 for d C = p(66) C = 66p So we supstitute 66p for C in NC = 1000 N(66p) = 1000 66pN = 1000 We solve for N by dividing both sides by 66p N = 1000/(66p) N = 500/(33p) N = 4.822877063 or a little less than 5 rotations.
