Question: A dynamometer is used to determine the power transmitted to the wheels of an electric car by simultaneously measuring the torque T and angular rotation

A dynamometer is used to determine the power transmitted to the wheels of an electric car by simultaneously measuring the torque T and angular rotation rate of the wheels. The power P is determined according to P = T . With the cars settings held constant, the following measurements are made: T (Nm)407388408414 (rad/s)4757473547774716(a)(2 points) Calculate the mean torque T and standard deviation of the torque, ST .(b)(2 points) Determine the random uncertainty of the torque, with 95% confidence. (c)(2 points) Calculate the mean rotation rate and standard deviation of the rotation rate S.(d)(2 points) Determine the random uncertainty of the rotation rate, with 95% confidence. (e)(2 points) Calculate the mean power P and standard deviation of the power SP .(f)(2 points) Determine the random uncertainty of the power, with 95% confidence. (g)(6 points) According to its manufacturer, the dynamometer measures both torque and rotation rate with accuracy 1% of the reading, with 95% confidence. Determine the systematic uncertainty in the power measurement. (h)(2 points) Determine the total uncertainty in the power measurement at 95% confidence. (i)(4 points) To reduce the total uncertainty, what would you do first? (j)(5 points) Which, if any, of the measurements of torque and rotation rate are outliers, according to Thompsons test?
