A 11 N horizontal force F→ pushes a block weighing 4.1 N against a vertical wall (see the figure). The coefficient of static friction between the wall and the block is 0.56, and the coefficient of kinetic friction is 0.49. Assume that the block is not moving initially. (a) Will the block move? ("yes" or "no") (b) In unit-vector notation Fxî+Fyĵ, what is the force on the block from the wall?
Problem 5: A painter (of mass 71 kg) needs to reach out from a scaffolding to paint the side of a building, so he lays a plank across two bars of the scaffolding, and puts a heavy bucket of mass 27 kg directly over one of the bars (see figure). You can assume the plank is massless, and is long enough to reach to the other building. L d If the bars are separated by a distance 1.5 m, how far, d, from the bar on the the right can the painter walk before the plank starts to fall? d= m 9 HOME sin() cos( cotan() asin() tan() П ( ) 7 8 acos() E ↑AAL 4 5 7* 1 2 3 6 atan() acotan() sinh()

A high-carbon steel with a fully pearlitic microstructure was used to form a high-strength bolt (H.-C. Lee et al., J. Mater. Proc. Tech. 211, 1044 (2011)). It was found that the bolt head had an average interlamellar spacing of 257 nm whereas the average spacing in the body of the bolt was 134 nm. Assuming that dislocation pileup is the primary mechanism responsible for the strength of this alloy, what ratio of strength (or hardness) might be expected in the head and body of the bolt?
What causes bandgaps in periodic elastic laminates? I've been trying to find an explanation for why bandgaps can form in periodic elastic laminates but so far I haven't found a good explanation. Can anyone point me to any resources which might provide an explanation or give a good analogy between this and other areas of physics where bandgaps may occur?
In the figure below, suppose the length L of the uniform bar is 3.50 m and its weight is 240 N. Also, let the block's weight W = 350 N and angle 0 30°. The wire can withstand a maximum tension of 500 N. C - X→ com В (a) What is the maximum possible distance x before the wire breaks? (b) With the block placed at this maximum x, what is the horizontal component of the force on the bar from the hinge at A? N (right) (c) What is the vertical component of this force? N (up)
I have tried 16.7x10^3, 16.7x10^4, and 1.365x10^8 and those are all wrong for the first part. I know that the second part is 14.3 hr. I need to know the km/s. Thank you!!
