A steel column has the following properties: Modulus of elasticity, E = 200 GPa, yield strength, Fy = 200 MPa, length, L = 12 m, moment of inertia, I = 37.7 x 10° mm* and area = 9,000 mm². Determine the following compressive stress if the column is fixed at both ends.

A drum with a 200-mm radius is attached to a disk with a radius of r A = 140 mm. The disk and drum have a combined mass of 5 kg and are suspended by two cords. Knowing that the acceleration of point B on the cord is zero, T A = 40 N, and T B = 20 N, determine the combined radius of gyration of the disk and drum. Fig. P16.55 and P16.56

The spring has a stiffness of k = 800 N/m and an unstretched length of 200 mm. Determine the force in cables BC and BD when the spring is held in the position shown. 400 mm A k= 800 N /m gram (FBD) a tan a =1 45* 4 a = 45° 300 mm X. 500 mm -400 mm- quilibrium

A flat plate is to be cast in an open mold whose bottom has a square shape that is 200 mm by 200 mm. The mold is 40 mm deep. A total of 106 mm3 of molten aluminum is poured into the mold. Solidification shrinkage is known to be 6.0%. The linear shrinkage due to thermal contraction after solidification is 1.3%.

A beam of I section 200 mm wide and 300mm deep with flange and web thickness 20 mm is used as a simply supported beam over a span of 7 m.the beam carries a distributed load of 5 kn/m over the whole span and a concentrated load of 20 kn at mid span determine the maximum bending stress set up and sketch the stress distribution.

A drum with a 200-mm radius is attached to a disk with a radius of r A = 150 mm. The disk and drum have a combined mass of 5 kg and a combined radius of gyration of 120 mm and are suspended by two cords. Knowing that T A = 35 N and T B = 25 N, determine the accelerations of points A and B on the cords. Fig. P16.55 and P16.56

A cantilever beam, 60 mm wide by 200 mm high and 6 m long, carries a load that varies uniformly from zero at the free end to 1000 N/m at the wall. 1. Solve the maximum flexural stress. 2. Solve the shearing stress developed in a fiber 40 mm from the top of the beam at wwwwn a section 3 m from the free end.

The 200-mm-radius disk rolls without sliding on the surface shown. Knowing that the distance BG is 160 mm and that at the instant shown the disk has an angular velocity of 11 rad/s counterclockwise and an angular acceleration of 3.5 rad/s² clockwise, determine the acceleration of A. (Round the final answer to two decimal places.)

A pipe 200 mm outside diameter and 20 m length is covered with a layer, 70 mm thick of insulation having a thermal conductivity of 0.05 W/m-K and a thermal conductance of 10 W/m²-K at the outer surface. If the temperature of the pipe is 350 deg C and the ambient temperature 15 deg C, calculate the external surface temperature of the lagging.

Its two ends are 40 mm and 30 mm in diameter and the length of each rod is 200 mm. The middle portion of the bar is 15 mm in diameter and 500 mm long. If the bar is subjected an axial tensile load of 15 kN, determine (1) Stress in each section, (2) Total extension.
