Learning Goal: To be able to analyze the equilibrium of systems subjected to frictional forces at belts and surfaces. When engineers design belt drives and band brakes, they engineer them to withstand the frictional forces that develop between the belts or bands and their contacting surfaces. These frictional forces lead to tensions on each side of the contacting surfaces that are unequal; the segment aligning with the motion of the belt or band has a greater tension Figure B 0 B HA 1 of 3 PC > Part B Blocks A and B have a masses of 160 kg and 290 kg, respectively. (Figure 2) The coefficient of static friction between A and B and between B and C is 0.290. The coefficient of static friction between the rope and peg E is 0.590. Pulley D rotates freely, and P = 16.0 N. If 0 = 60.0 degrees, what is the smallest magnitude, T, of tension, T, that causes block B to move? Express your answer numerically in kilonewtons to three significant figures. View Available Hint(s) IVE ΑΣΦ | 11 T = 6.93…
Match the following to True/False. A. GPS devices are an example of mobile traffic sensors For the time-space diagram of a single-lane one-way road, the vehicle trajectories do not intersect with each other unless there is a crash. Pneumatic tubes detect vehicle presence by sending an electric signal to a roadside device. B. Space mean speed may be greater than time mean speed in certain situations. A. True B. False

Determine the moment caused by force F1 about point O. (N-m) A = 4 17. Determine the moment caused by force F2 about point O. (N-m) B = 5 18. Determine the resultant moment about point O. (N-m) C = 6
A driver traveling at 70 mph on an interstate highway shift his eyes from left to right and focuses on a deer standing on the shoulder. Estimate the distance in feet the vehicle travels as the driver's eyes shift and fixate.
In comparison with normal drivers, drivers under the effects of drugs or alcohol . stopping .sight distance usually require more perception-reaction time and hence need the same .a shorter .b longer .c
The motion of a particle is defined by the relation x=t3-6t2-36t-40, where x and t are expressed in feet and seconds, respectively. Determine: a)when the velocity is zero b)the velocity, the acceleration, and the total distance traveled when x=0. 1:46 AM

11. Skid Marks Law enforcement officials sometimes use the formula s =√30FB to determine a car's speed, s, in miles per hour, from a car's skid marks. The F in the formula represents the "road factor," which is determined by the Ted's surface, and the B represents the braking distance, n feet. Officer Jenkins is investigating an accident. Find the car's speed if the skid marks are 80 feet long and a) the road was dry asphalt, whose road factor is 0.85, b) the road was wet gravel, whose road factor is 0,52.

TM Ford® Mustang Cobra time-to-speed data for a 1994 Ford Mustang Cobra accelerating from rest to 130 mph. How far had the Mustang traveled by the time it reached this speed? (Use trapezoids to estimate the area under the velocity curve, but be careful: The time intervals vary in length.) The accompanying table shows Speed change Time (sec) 2.2 Zero to 30 mph 40 mph 50 mph 60 mph 70 mph 80 mph 90 mph 100 mph 110 mph 120 mph 130 mph 3.2 4.5 5.9 7.8 10.2 12.7 16.0 20.6 26.2 37.1
The cars travel over a 60m section of highway at constant speeds of 19, 20,and 25 m/s. a. Compute the time mean speed.b. Compute the space mean speed.
