In about 1915, henry sincosky of philadelphia suspended himself from a rafter by gripping the rafter with the thumb of each hand on one side and the fingers of the other side. sincosky's mass was 79 kg. if the coefficient of static friction between hand and rafter was 0.52, what was the least magnitude of the normal force on the rafter from each thumb or opposite fingers? (after suspending himself, sincosky chinned himself on the rafter and then moved hand-over-hand along the rafter. if you do not think sincosky's grip was remarkable, try to repeat his stunt.)

Suppose that an electromagnetic wave which is linearly polarized along the x−axis is propagating in vacuum along the z−axis. the wave is incident on a conductor which is placed at z > 0 region of the space. the conductor has conductivity σ, magnetic permeability µ and electric permittivity ε. (a) find the characteristic time for the free charge density which dissipates at the conductor. (b) write the maxwell equations and derive the wave equation for a plane wave propagating in a conductor. (c) find the attenuation distance at which the incident amplitude reduces to e ^−1 of its initial value. (d) find the electric and magnetic fields inside the conductor. 8 (e) find the power loss per area of the incident electromagnetic wave at the surface of conductor.
