If the pulley system shown is in equilibrium, determine the tension in the cable and the normal reaction of the smooth plane on Block W1 using the method of rectangular components. w1 7 w1-FS w2 20 NR = (1 decimal place) T= W2 = (1 decimal place)In the figure below, both the ceiling and the ruler accelerate together at 1.6 m/s2 in the +y direction, and the reading to the "new" length of the vertical wire is as indicated. Ignore the effect on the two diagonal wires. Other parameters are below: Weight of the pan = 5 N Weights (or loads) = 74 N Originally, the wire has a length 0.200 cm, and diameter of 2.7 cm. Calculate the Young's modulus of the wire in Pa. NOTES: Use pi = 3.14. Final answer in ZERO decimal place. 4.000 4.100 4.200 4.300 cmA 4 m long horizontal uniform beam of mass 20 kg is supported by a wire as shown in the figure. The wire makes an angle of 23 degrees with the beam. Attached to the beam 1.2 m from the wall is a ball with a mass of 48 kg. What is the tension in the string? K 0 (m)
- Refer to the procedure part. Assume Xcm= 50.0 cm, 150.0 g is suspended from a hanger clamp at the position x = +15.0cm, and a hanger clamp is at position x =- 75.0 cm. If each hanger clamp has amass m = 16.5 g, what mass must be added to negative x position in order to attain stable equilibrium? Sketch a diagram of the situation (refer to Figure below). Compute for the torque and moment of inertia. ... 75 cm 15cm Mass=150 gA student gets his car stuck in a snow drift. Not at a loss, having studied physics, he attaches one end of a stout rope to the vehide and the other end to the trunk of a nearby tree, allowing for a small amount of slack. The student then exerts a force F on the center of the rope in the direction perpendicular to the car-tree line, as shown in the figure below. If the rope is inextensible and if the magnitude of the applied force is 504 N, what is the force on the car? (Assume equilibrium conditions.)
