Lifting is a manual or mechanical handling process of raising a load above its level for the purpose of changing its location and improper lifting causes accidents in oil and gas industry. In order to avoid the accidents how proper manual lifting (4marks) is done if not done what happens (1mark).

A siphon consisting of a pipe of 15cm diameter is used
to empty kerosene oil (s = 0.8) from a tank A.
The siphon discharges to the atmosphere at an elevation of 1m. the
oil surface in the tank is at ana
elevation of 4m. The centerline of the siphon pipe at its highest
point C is at an elevation of 5.5m. The
losses in the pipe are 0.5m up to the summit and 1.2m from the
summit to the outlet. Estimate:
i. The discharge in the pipe
ii. Pressure at point C
iii. Length of the pipe given f = 0.0035

4. Assume that ball A of weight W is released from rest in the position ?ଵ ൌ 60° and swings downward to where it strikes the at-rest ball B of weight 3W . Assuming an elastic impact, calculate
(a) the angle ?ଶ through which the lager pendulum (Pendulum B) will swing after the impact.
(b) The total energy loss just after impact The length of the rods for both pendulum A and B are equal to ?.
You may assume W =196.2 N and ? = 1 m for numerical calculations.

1) Humans have populated regions in which the geomorphic settings pose hazards for construction and engineering projects. Discuss the extent to which the potential hazards are caused by intrinsic versus extrinsic thresholds. Build your discussion around comparing and contrasting humid, semi- arid, glaciated, and periglacial environments.

A hydraulic punching machine is used to make holes in a plate
using two steel punches having
different diameter. By applying a compressive stress of 37 x103
kN/m2 using a punch of diameter
50 mm, the maximum shear stress developed in the plate was found to
be 290 N/mm2. Suggest the
value for thickness for the plate suitable for this loading
condition.
What will be the change in the shear stress when a compressive
force of 85 kN is applied on the
plate of same thickness using another punch having diameter 12%
more than the first one? Check
which one of the steel punches used is safe against shear, if the
permissible safe shear stress on
the plate based on the design conditions is limited to 300 N/mm2.
Based on the results, discuss
how the thickness of the plate and the diameter of the punch can be
modified to withstand the safe
shear stress.

Deflection tests were conducted on a steel joist and a timber
joist both simply supported over
a span of 5 m and carrying a point load of 45 kN at distance of ‘a’
from left support. Maximum
deflection was observed at a position 2.4 m from the left support
for steel joist and 1.85 m from
the left support for steel joist. Calculate and compare the results
for maximum deflection, slope at
both ends and deflection under the load for both steel and timber
joists. Take Flexural rigidity for
steel joist as 14 x 1012 Nmm2 and the Flexural rigidity for timber
joist as 6.9 x 1012 Nmm2. Suggest
the changes to be made in the dimensions of the beam for reducing
the deflection based on the
results obtained.
