- Determine the minimum coefficient of static friction between the tires and the road surface so that the 1.5-Mg car does not slide as it travels at 80 km h on the curved road. Neglect the size of the car. > Free-Body Diagram:The frictional force F f developed between the tires and the road surface and a
- See the answer. Detrmine the minimum forcee P to prevent the 30-kg rod AB from sliding. The contact surface at B is smooth, whereas the coefficient of static friction between the rod and the wall at A is Us=0.2. Please explain in detail, Thanks. Show transcribed image text.
- Multiple Objects qA block of mass m1 on a rough, horizontal surface is connected to a ball of mass m2 by a lightweight cord over a lightweight, frictionless pulley as shown in figure. A force of magnitude F at an angle θwith the horizontal is applied to the block as shown and the block slides to the right.
- 0.30/1.30 = 514.9 MPa. 12.3 A particular metal has a flow curve with strength coefficient = 35,000 lb/in2 and strain-hardening exponent = 0.26. A tensile specimen of the metal with gage length = 2.0 in is stretched to a length = 3.3 in. Determine the flow stress at this new length and the average flow stress that the metal has been subjected to
- AB and BC are attached as shown. Knowing that the tensions in cables AB and BC are 555 N and 660 N, respectively, determine the moment about O of the resultant force exerted on the tree by the cables at B.
- following magnitudes and directions of P, determine whether the block moves, the direction of motion, and the magnitude and direction of the frictional force acting on the block: (a) 34N up (b) 12N up, (c) 48N up, (d) 62N up, (e) 10N down, (f) 18N down. F=60N (a) P=34N, up mg=22N N N=F=60N P 22N f Without P, the block is at rest f f N Block ...
- gravitational force and that the moon is moving with a constant speed in a circular orbit around the earth. The mass of the earth is . The mass of the moon is . The radius of the orbit is . m e=5.98×10 24kg m m=7.36×10 22kg r e,m=3.8×10 8m
- A force acts along the displacement of the asteroid and slows it down. The asteroid has a mass of 6.0× 104 kg, and the force causes its speed to change from 7400 to 5900m/s. (a) What is the work done by the force? (b) If the asteroid slows down over a distance of 2.3× 106 m determine the magnitude of the force.
- 8. (24 pts) A block of mass m 105.0 kg, starting from rest, slides down a ramp making an angle a 320 with respect to horizontal. The ramp is 5.0 meters long. A constant frictional force of 190.0 N acts throughout the motion, and a force F is being applied by a rope as shown ill order to prevent the block from sliding too fast. m Ccsoq
