The pole in the figure is a a 90° bend in a power line and is therefore subjected to more shear force than poles in straight parts of the line. The tension in the two wires at the top of the pole is 3.5 × 104 N, and both wires are at an angle of 80° with respect to the pole. The pole is 15 m tall, has an 16 cm diameter and can be considered to have half the strength of hardwood (hardwood has a Young's modulus of 1.5×1010 N/m2 and a shear modulus of 1×010 N/m2). First ignore the guy wire (Tgw). Calculate the compression of the pole, in millimeters?

Still ignoring the guy wire, Find how much it bends in mm to the right?

Now find the tension in the guy wire used to keep the pole straight if it is attached to the top of the pole at an angle of 30° with the vertical in Newtons? (The guy wire must be in the opposite direction of the bend.)

Glass is transparent to visibile light under normal conditions; however, at extremely high intensities, glass will absorb most of the light incident upon it. this works through a process known as multiphoton absorption. in this process, several photons are absorbed at the same time. if very intense light whose photons carry 2ev of energy is shined onto a material with a band gap of 4ev, that light can be absorbed through two-photon absorption, because two photons have the right amount of energy to bridge the band gap. what is the minimum number of photons of 800-nm light that are needed to equal or exceed the band gap of fused silica glass
