A prony brake is to be built to measure the torque output of a 10-hp motor that operates at a speed of 1200 r/min. If the scale available has a maximum capacity of 7kg, what is the length of the shortest brake arm that could be used to measure any torque output of the motor up to 125 percent of its rated value?

Solve for the indicated value, and graph the situation showing the solution point. The formula for measuring sound intensity in decibels D is defined by the equation D = 10 log (1) using the common (base 10) logarithm where I is the intensity of the sound in watts per square meter and Io = 10-12 is the lowest level of sound that the average person can hear. How many decibels are emitted from a jet plane with a sound intensity of 8.7. 102 watts per square meter? Round your answer to three decimal places. The jet plane emits Number decibels at 8.7. 102 watts per square meter.

A digital meter is used to determine the torque of a rotating shaft using single toothed flanges and inductive pick-ups. Static calibration show that the flange twist by an angle of one degree for an applied torque of 1000 Nm. In a test with the shaft rotating at 500 r.p.m., the torque calculated from the timer readings is 1200 Nm. What is the maximum possible error of final digit on the timer display represents units of 10^-5 se and accuracy of instrument specified 0.05% of the reading ± 1 in the final digit?

A 150.00-mm sine bar is used to inspect a part angle that has a dimension of 35.0° ± 1.0°. The sine bar rolls have a diameter = 25.0 mm. A set of gage blocks is available that can form any height from 10.0000 mm to 199.995 mm in increments of 0.005 mm. All inspection is performed on a surface plate. Determine (a) the height of the gage block stack to inspect the minimum angle, (b) the height of the gage block stack to inspect the maximum angle, and (c) the smallest increment of angle that can be set up at the nominal angle size
