) Using the table below, determine the stability class (A-F) of the following conditions: (a) ground temperature is 55°F, temperature at 900 ft is 66°F; (b) ground level temperature is 65°F and temperature at 1700 ft is 54°F; (c) at the ground temperature is 26°C and at 400 m t is 19°C; (' +

2. The steel frame shown in Figure M-1 supports a rotating machine that exerts a horizontal force at the girder level F (t) = 200 sin 7.2t Ib. Assuming 8% of critical damping, E = 29,000 ksi and I = 75.3 in“, determine the following: Stiffness, k = Frequency ratio, r = Maximum Static Deformation, (Ust)o =

The standard length of a tape is 100m having a weight of 1.2kg with the standard temperature of 20 ̊C and standard pull of 5.5kg. The young modulus of elasticity of the tape is 200GPa, cross sectional area is 2.8mm2 and the coefficient of linear expansion is 0.0000116/ ̊C. Determine the normal tension of the tape. Hint: The normal tension of a tape is the applied tension which will cause the effects of pull and sag to neutralize each other.

A leaf spring I m long is made up with steel plates with width equal to 6 times its thickness. Design the spring for a load of 15 kN when the maximum stress is 100 MPa and deflection is not to exceed 16 mm.
