To calculate the torques, we need to determine the lever arms for each of the forces. These lever arms are shown in the following drawings:
(a)We find that the magnitude of the torque due to weight W is
Magnitude of Torque = W lw = (13600N)(2.50m) sin 32.0o = 18017.25 N.m
(b) The magnitude of the torque due to thurst T is
Magnitude of Torque = T lT = (61000N)(2.50m) cos 32.0o = 129327.33 N.m

Q7. Consider the twin-jet airplane described as follow: wing area = 47 m2, aspect ratio = 6.5, Oswald efficiency factor = 0.87, weight = 103,047N, and zero-lift drag coefficient = 0.032. The airplane is equipped with two jet engines with 40,298 N of static thrust each at sea level. The thrust-specific fuel consumption is 1.0 N of fuel per newton of thrust per hour, the fuel capacity is 1900 gal, and the maximum gross weight is 136,960 N. Calculate the...

The figure shown below
represents a simplified model of a jet engine mounted to a wing
through a mechanism that acts as a spring of stiffness k and has a
mass ms. Assume the engine has a moment of inertia J and mass m and
that the rotation of the engine (i.e. the vectoring of the engine)
is related to the vertical displacement of the engine, x(t), by the
radius, ro (i.e. x=ro). Calculate the equation of motion, x(t) of...

A U-tube contains liquid of unknown density. An oil of density
770 kg/m³ is poured into one arm of the tube until the oil column
is 13.5 cm high. The oil-air interface is then 4.5 cm above the
liquid level in the other arm of the U-tube. Find the density of
the liquid.
