In beam modelling with Pinnacle RTPS, What is the role of the
flattening filter? What is the advantage of flattening filter free
and what is the main restriction.
In beam modelling with Pinnacle RTPS, What is the definition of
a “harder spectrum”? How would a “harder” 6MV spectrum change
theshape of the corresponding percentage depth-dose curve?
In beam modelling with Pinnacle RTPS, The source size is defined
to give geometric penumbra width, explain what else contributes to
thepenumbra width? Explain why width of D80-20 is used
to characterise penumbra width? Would the D80-20be
wider or narrower at high energy and why?
In beam modelling with Pinnacle RTPS,
For a 6MV beam:a) What is the maximum photon energy?b) What is
the mean (roughly) photon energy?c) How does the spectrum affect
the depth dose penetration?
A beam with a cross-section of 0.3 m x 0.7 m has an effective
depth of 0.638 m and a span of 4.30 m. Use the following data below
to determine (a) the steel requirement due to flexure, (b) ultimate
threshold torsion, and (c) spacing of stirrup due to combined shear
and torsion:
Mu = 322 KN-m
Vu = 317 KN
Tu = 42 KN-m
f'c =28 MPa
fyt = 414 MPa
12 mm stirrup diameter
cover of 0.04 m
Instructions: Be sure to define all parameters and random
variables used. Also, you must provide any code you use (final
computed values are not sufficient). I strongly recommend that you
create Jupyter Notebooks for this assignment, embedding your
written comments in Markdown cells.
4. A researcher conducts an experiment in a residence
for senior citizens to investigate the effect of floor type on the
risk of fall-related injury. For 24 randomly selected individuals
in the facility, she records the type...

6. A biologist wishes to examine the collision
avoidance behaviour of bullfrogs housed in experimental boxes. He
placed an object in the upper visual field of each frog and then
moved the object progressively closer until the...
