A scrap metal dealer near your school needs to sort magnetic metal, non-magnetic metal into separate piles for recycling. He has asked you to design a CRANE with an electromagnet to sort these metals. Follow the design process when designing the crane.

Give the steps by steps explanation of the previous answer

(b) The mass of the object suspended at G is 100 kg, as demonstrated in Figure Q5(b). Determine the reaction on member CDE at C and E.

fill in the blanks   When an element has its proper complement of valence electrons, it is electrically _________; when an atom has more or fewer than that number, it is an ion and has an electric charge. The charge is ________ when extra electrons are present and ________  when some are missing. .The ____________ bond is formed among metallic atoms when some electrons in the valence shell separate from their orbital path and exist in a free state like a cloud or gas. Surrounding the positive nuclei in this highly mobile state, the negative cloud bonds the atoms together. Because the electrons in the cloud do not “belong” to any particular atoms, the bond strengths can vary, deformation can take place without rupture, and good heat and electrical conductivity can occur owing to the easy movement of electrons from one atomic site to the next. This type of bonding makes possible some of the useful characteristics of metals, both mechanical properties and physical properties.

How many Iron atoms are there in 2000 pounds of Iron?

2. Circle the answer. True/False: For both central and oblique impact problems, the following equations apply along the line of impact (for this problem, assume LoI is along x-direction): Σ m(vx)1 = Σ m(Vx)2 e = [(VBx)2-(VAX)2]/[(VAX)1 − (VBx)1]
