An airplane has an effective wing surface area of 19.0 m2 that
is generating the lift force. In level flight the air speed over
the top of the wings is 55.0 m/s, while the air speed beneath the
wings is 35.0 m/s. What is the weight of the plane?

A flying wing has a planform area of 3700 ft2, a root
chord at the airplane centerline of 34 ft, an overall taper ratio
of 0.275, and a span of 170 ft. The average weighted airfoil
thickness ratio is 10.2% and the wing has 36 degrees of sweepback
at the 25% chordline. The air- plane is cruising at a pressure
altitude of 17,000 ft on a standard day with a wing loading of 40
lb/ft2. The cruise Mach number is...

Design a rectangular reinforced concrete beam for a simple span
of 35 ft. Uniform service loads are 1.0 kip/ft dead load (excluding
the self-weight of the beam) and 1.2 kips/ft live load. Use
f′c=4,000 psi and fy=60,000 psi. Sketch your design.

Design a rectangular reinforced concrete beam for a simple span
of 32 ft. Uniform service loads are 1.5 kips/ft dead load and 2.0
kips/ft live load. Assuming that the total depth h is not to exceed
32 in. and that there is no limitation on the width b. Use f′c =
3000 psi and fy = 60,000 psi. Sketch your design

A beam 3m long is simply supported at its ends. The beam is
loaded with a downward vertical load of 200N at a point 2m from the
left support.
USING AMM.
a.) The maximum deflection is located at what distance from the
left support? Answer: 1.63m
b.) Calculate the maximum deflection assuming E = 50 GPa and I =
1x10^6 mm4 Answer 2.9mm

A beam 3m long is simply supported at its ends. The beam is
loaded with a downward vertical load of 200N at a point 2m from the
left support.
Using DIM:
a. The maximum deflection is located at what distance from the
left support?
b. Calculate the maximum deflection assuming E = 50 GPa and I =
1x10^6 mm4

A 12 in. x 18 in. rectangular beam has an effective span of 20
ft. A dead load of 1500 lb/ft (includes self weight) and a live
load of 4000 lb/ft is applied to the beam. The concrete and steel
strengths are 4000 psi and 60000 psi respectively. Design and
detail the shear reinforcement for the beam. Assume d is 2 inches
less than h

Problem 2: A simple roof beam with a span 30 ft has a tributary
width of 5 ft. The nominal loads that act on the roof system are
shown below. Using the ASCE 7 Strength Design load combinations
determine the factored design load in the beam (plf). Show all load
combination calculations and identify the controlling load
combination and resulting design values for positive and negative
moment (±Mu) and shear (Vu).

A uniform beam is 5.00 m long and has a mass of 53.0 kg. The
beam is supported in a horizontal position by a hinge and a cable,
with angle ? = 115°.
(a) Draw all the forces acting on the beam.
(b) Label the axis of rotation and the position vectors of each
point of action.
(c) What is the tension on the cable?
(d) What are the magnitude of the vertical and horizontal forces
acting on the hinge?...
