The tasks are to find equations for:
dG/(dV_Out )
(d^2 G)/〖dV_Out〗^2
(a) For the beam loaded as shown in Fig. 1, determine the maximum Bending
Moment and Shear Force (present this in form of SF and BM diagrams)
(b) Using some of the information above, determine suitable cross-sectional
dimensions for effective depth and width of the beam. Assume overall cover to
reinforcement as 25 mm.
(c) Taking fcu as 25 N/mm2
, fy as 460 N/mm2
and fyv as 250 N/mm2
, design the beam
for:
(i) Bending
(ii) Shear
Fig. 1
(d) Draw a detailed reinforcement drawing showing elevation and typical cross-
section of the beam.
What is the factor for expansion and contraction of materials
A. It is supported by a pin at D and a short aluminum EF. A steel wire BC having an
unstretched length of 110 mm is also supporting the rigid link at C. The cross sectional
area for the steel wire BC is 35.50 mm2
. On the other hand, a short aluminum block EF
having unloaded length of 75 mm and cross sectional area of 40 mm2
. The elastic
modulus for steel and aluminum are 200 GPa and 70 GPa, respectively.
i) Determine the average normal stress in the steel wire BC and aluminum block.
ii) Determine the displacement for points B and E of the link subjected to the vertical load applied.
A field is in the form of a regular pentagon. It is required to determine the directions of bounding sides which are referenced from an assumed meridian 05°30’ to the right (easterly) of the true meridian. If the assumed bearing of side AB is N 33°20’W, determine the true azimuths (from south) of the following sides of the field: AB, BC, CD, DE and EA. Assume that the corners are labeled in a counterclockwise direction.
Tabulate answers in a convenient format.
