Heat shielding calculation
595398 Heat shielding calculation How much more effective will a double layered heat shield (.1mm stainless steel outer shell (facing radiant heat source), .5 mm inner aluminum shell, and 4mm air gap) be at blocking thermal radiation then a single 2mm

Gamma radiation
If shielding is considered as a means of control, how many centimeters are needed to reduce the radiation to 1% of what a worker would be exposed to without shielding?
Assume the shielding material is (a) concrete, (b) steel and (c) lead.

Absorption loss of metal shielding
Dear Student,
Absorption loss of shielding in a metal is given by,
A= (3.338e-3)*t*sqrt(u*f*G)
where,
A is absorption loss in db
t is thickness in mils
G is the relative conductivity compared to copper
u is relative permeability compared to

Effective rates of protection
Calculate the effective rate of protection if there is no import tariff on the imports of either steel or copper.
d. Suppose there is import duty of 20% and 15% on imports of steel and copper, respectively.

Methods for the elastic and plastic evaluation of steel structures
Above test comparison will show that with increase in carbon content in steel, the fracture decreases Ultimate strength of steel increases, but at the same time elogation before since with increase in carbon % the steel specimen
actually loses its ductility
