Find the uncertainty in the moment of interia. Moment of interia of a disk depends on mass and radius according to this function I(m,r) = 1/2 m r. Your measured mass and radius have the following uncertainties Sm = 4.17 kg and Sr = 0.71 m. What is is the uncertainty in moment of interia, %3D S1, if the measured mass, m = 14.77 kg and the measured radius, r= 11.3 m? Units are not needed %3D

The heat transfer conducted through material is calculated from the equation: Q = KX AXTD/L Where K: Conductivity of material A: Area of heat transfer TD: Temperature difference across material L: Thickness of material A student measures the area, thickness and temperature difference and assumes that the error in conductivity is negligible. The student also estimates the uncertainty range for each variable. In estimating the maximum possible value of Q, the student should use the following formula: A B Q max= K x A max x TD max / L max Q max= K x A max x TD max / L nom Q max= Q nominal + dQ/dLmin Q max= K x A max x TD max / L min

The figure below (for illustrative purposes) shows a perfectly rigid (non-deformable) beam which is perfectly rigidly supported at points P and R by two force measurement scales, 1 and 2. PQ is 65 cm and PR is 150 cm. The beam is horizontal when each of scales 1 and 2 gives a reading of zero. Acceleration due to gravity is 9.81 ms-2. Scale 1 Point P Point Q Point R Scale 2 Choose one of the following options that will give the correct readings of scales 1 and 2 when a mass of 30 kg acts vertically downwards at point Q. (The scales are not loaded to you will have to calculate the answer) O A Reading of Scale 1 = 150 kg; Reading of scale 2 = 65 kg O B. Reading of Scale 1 = 166.77 kg; Reading of scale 2 = 127.53 kg O C. Reading of Scale 1 = 150 Newton; Reading of scale 2 = 65 kg O D.

The "spring-like effect" in a golf club could be determined by measuring the coeffi cient of restitution (the ratio of the outbound velocity to the inbound velocity of a golf ball fired at the clubhead). Twelve randomly selected drivers produced by two clubmakers are tested and the coefficient of restitution measured. The data follow: Club 1: 0.8406, 0.8104, 0.8234, 0.8198, 0.8235, 0.8562, 0.8123, 0.7976, 0.8184, 0.8265, 0.7773, 0.7871 Club 2: 0.8305, 0.7905, 0.8352, 0.8380, 0.8145, 0.8465, 0.8244, 0.8014, 0.8309, 0.8405, 0.8256, 0.8476 Test the hypothesis that both brands of ball have equal mean overall distance. Use a = 0.05 and assume equal variances. Answer the following questions regarding the t-test. 1. How many degrees-of-freedom are there in this problem (needed for finding the critical t- values). 2. What is the absolute values of the critical t-value for this problem? We are using a two- tailed t-test with a significance level of 5%. (use four significant figures) 3. What is…
