The pole in the figure below is at a 90° bend in a power line and is therefore subjected to more shear force than ones in straight parts of the line. The tension in each line is 4.60 x 10" N, at the angles shown The pole is 15.0 m tall, has a 16.0 cm diameter and can be considered to have 5.0 X10 N/m? the strength of hardwood. Assume Young's modulus to be 7.5 X10 N/m and the shear...

. A very fast runner is carrying a pole that is 20m in length when at rest. The runner runs toward a barn that is 10m in length when at rest. We will call event A the time/location where the leading edge pole enters the barn. Event B is when the trailing edge of the pole enters the barn. Event C is when the leading edge of the pole leaves the barn. Event D is when the trailing edge of...

A uniform pole of weight 13.0 N is propped between the floor and the ceiling of a room. The height of the room is 2.82 m, and when the pole is in equilibrium, the friction force between the base of the pole and the floor is 19.5 N. The normal force on the pole from the floor is 35.0 N. (a) What is the length (in m) of the longest pole that can be propped between the floor and the...

2. Shunt capacitors are installed at the receiving end to improve the line performance of Q1. The line delivers 70 MVA, 0.8 lagging power factor at 64 kV. Determine the total Mvar and the capacitance per phase of Y-connected capacitors when the sending end voltage is a) 69 kV b) 64 kV *Hint: Use (5.85) and (5.86) (H. Saadat] to compute the power angle and the receiving end reactive power.
