from a certain engine measurements are taken of the torque m in Nm with increasing speed (rounds per minute rpm)results are written below.

rpm 2000 2500 3000 3500 4000 4500 5000

M. 65 92 139 150 170 175 218

the model parameters for simple transgression in least squares sense are: y intercept = -19.8571 and slope = 0.0469 SSE = 749.71

1. what is the average torque at 3500 rpm?

2. what is the confidence interval for slope beta1 with alpha = 0.05. comment on these findings. use SSxx =7.10^6

3. calculate the coefficient of correlation.

A certain engine develops an output torque of 1800 + 200sin2?? Nm, where ? is the crank angle measured from some datum. This engine drives a machine which requires a driving torque of 1800 + 300sin?? Nm. The rotating parts have a mass of 100 kg, with a radius of gyration of 0.25 m. The maximum speed of the rotating parts is observed to be 250 rev/min. a) Sketch both the driving and load torque curves on the same axes...

1. A particle starts from rest, increasing its speed evenly, traveling a distance of 10.0 (m) in a time of 1.40 (s). From that moment it is kept at constant speed for 1.00 (s). Then its speed decreases to rest in a time of 2.80 (s). Calculate the total displacement of the particle. STEP BY STEP PLEASE

: A dc motor develops 55 N-m torque at a speed of 600 rad/s when 12 volts are applied. It stalls out at this voltage with 100 N- m of torque. If the inertia and damping of the armature are 7 kg-m2 and 3 N-m -s/rad, respectively, find the transfer function, G(s) = θL(s)/Ea(s), of this motor if it drives an inertia load of 105 kg-m2 through a gear train, as shown in the figure 11.
