Question: A fixed-end beam is subjected to a concentrated load at the midspan P.= 200 Ib, as shown in Figure. The beam has a rectangular cross section with width =12 in; and height =1 in. The length of the beam is L =200 in and its modulus of elasticity is E = 107 lb/in2, Taking advantage of symmetry, use only one beam element to determine the maximum bending and shear stresses in the beam.

A barge on the Ohio river is 35 ft wide and 200 ft long with walls which are 12 ft high. One day you see it going up river empty and 10.5 ft of the barge is above water. What is the mass of the barge
A 3.50nC point charge is placed at the centre of a hollow metal sphere that has an inner radius 4.90cm and an outer radius 12.0cm. The metal sphere itself is charged to 7.00nC. How much charge is on the outside surface of the hollow sphere? How much ..
Let us approximate an electron in the n-th shell of an atom as being like an electron in the n-th shell of a hydrogen atom with an effective nuclear charge Z. Use your knowledge of the hydrogen atom to calculate the ionization energy of this elect..
A meter stick is pivoted at its 50-cm mark but does not balance because of non uniformities in its material that cause its center of gravity to be displaced from its geometrical center. Find the mass of the meter stick and its location of its cente..
