Multiple ChoiceA 2-m long bar is free to rotate about an axis located 0.7 m from one of its ends. Two forces act on the bar, F1 = 100 N and F2 = 200 N, and both make 30° with the bar. Find the Net Torque on the bar. Use +/− to indicate direction.825views12rank6commentsHas a video solution.
Textbook QuestionThree forces are applied to a wheel of radius 0.350 m, as shown in Fig. E10.4. One force is perpendicular to the rim, one is tangent to it, and the other one makes a 40.0° angle with the radius. What is the net torque on the wheel due to these three forces for an axis perpendicular to the wheel and passing through its center? 1337views1rank1commentsHas a video solution.
Textbook QuestionA 1.0 kg ball and a 2.0 kg ball are connected by a 1.0-m-long rigid, massless rod. The rod is rotating cw about its center of mass at 20 rpm. What net torque will bring the balls to a halt in 5.0 s?2247viewsHas a video solution.
Textbook QuestionAn object's moment of inertia is 2.0 kg m^2. Its angular velocity is increasing at the rate of 4.0 rad/s per second. What is the net torque on the object?547viewsHas a video solution.
Textbook QuestionA satellite follows the elliptical orbit shown in FIGURE P12.77. The only force on the satellite is the gravitational attraction of the planet. The satellite's speed at point 1 is 8000 m/s. a. Does the satellite experience any torque about the center of the planet? Explain.290viewsHas a video solution.
Textbook Question(II) Determine the net torque on the 2.0-m-long uniform beam shown in Fig. 10–56. All forces are shown. Calculate about(b) point P at one end.<IMAGE>51viewsHas a video solution.
Textbook QuestionIf the coefficient of static friction between a car’s tires and the pavement is 0.65, calculate the minimum torque that must be applied to the 66-cm-diameter tire of a 1250-kg automobile in order to “lay rubber” (make the wheels spin, slipping as the car accelerates). Assume each wheel supports an equal share of the weight.62viewsHas a video solution.
