Determine the angle which the string would make with the horizontal,whan weights of the blocks A and B are such that
(a)WA=WB=W and
(b)WA=W,WB=2W.
A bar AB is hinged to the foundation at A and supported by strut CD is subjected to a horizontal 50 kN load at B,as shown in fig Determine the nature and magnitude of the forces in strut and also the reaction at A
for a pure sinosudial wave. what is the value of form factor and peak factor
A hollow circular tube T of length L = 15 in. is uniformly
compressed by a force P acting through a rigid plate (see
figure). The outside and inside diameters of the tube are
3.0 and 2.75 in., respectively. A concentric solid circular
bar B of 1.5 in. diameter is mounted inside the tube.
When no load is present, there is a clearance c _ 0.010
in. between the bar B and the rigid plate. Both bar and
tube are made of steel having an elastoplastic stress-
strain diagram with E = 29 x 103 ksi and 𝜎Y = 36 ksi.
(a) Determine the yield load PY and the corresponding
shortening ẟY of the tube.
(b) Determine the plastic load PP and the corresponding
shortening ẟP of the tube.
Knowing that a 0.02-in. gap exists when the
temperature is 75℉, determine (a) the temperature at
which the normal stress in the aluminum bar will be
equal to - 11 ksi, (b) the corresponding exact length
of the aluminum bar.
The steel rod is stress-free before the
axial loads P1 = 150 kN and P2 = 90 kN
are applied to the rod. Assuming that the
walls are rigid, calculate the axial force in
each segment after the loads are applied.
Use E = 200 GPa.
The block shown is made of a magnesium alloy
for which E = 45 GPa and v = 0.35. Knowing that
𝜎x = -180 MPa, determine (a) the magnitude of 𝜎y
for which the change in the height of the block will
be zero, (b) the corresponding change in the area
of the face ABCD, (c) the corresponding change
in the volume of the block.
A steam turbine receive a steam flow of 13kg/s and the power output is 500kw calculate
a. The chance specific enthalpy across the turbine when velocity at entrance and exist and the difference in elevation negliable
b. The chance specific enthalpy when the velocity of entrance is 60m/s, The velocity of exist is 36m/s and inlet pipe is 3m above the exhausted pipe.
dielectric with a positive charge of 5 C has 18.75 × electrons added to it. What is the net charge
The intersecting edges of a nonorthogonal parallelepiped are defined by the
position vectors TR/A=-20 T+ 30 j + Sk, TOA=8™+ 25 j+ 10k, DA = 4T - 2 j-15k
mm. Determine the volume of this object.
