CE 270 - Final Exam Problem No. 1. (20 points) A rectangular cross-section that is 50 mm wide and 250 mm deep is subjected to shear force of 22 kN‚ axial force (tension) of 16.5 kN and bending moment of 33 kN-m. Calculate and show the stress diagrams in the cross-section. What is the maximum normal stress‚ and where does it occur. What is the maximum shear stress and where does it occur. Problem No. 2 (20 points) Determine the principal stress‚ the maximum in-plane shear stress

Section A How does the engine size(capacity) of a motor car relate to the acceleration of the car? Hypothesis: The acceleration of a car will increase if the size(capacity) of the engine increases. The car with the biggest engine capacity will take the fastest to reach the velocity of 60km/h from rest position. Method: 1) Arrange to use three different hatchback cars with different engine capacities‚ but

intake does not see as high a pressure as it would want thus this delay in the power delivery is known as "lag". To reduce lag‚ one of the direct way is to simply use a smaller turbocharger as the turbines are smaller and lighter‚ it has lesser inertia and thus takes a shorter time to spool up. However due to the smaller size‚ the volume of air that it can take in for compression is restricted at high end and thus the performance is choked. Vice-versa to allow more air to be compressed and thus

It is structured with the conceptual approach. The broad concepts of matter‚ position‚ motion and time; energy; waves; fields; Atomic and Nuclear Physics‚ electronics are considered and each concept forms a part on which other subconcepts are further based.

1.1 SYNCHRONOUS GENERATOR THEORY The synchronous generator‚ like all generators works on the principle that when a coil is placed in varying magnetic field‚ an emf is induced in the coil. Synchronous Generator consists of two main windings‚ the armature winding and the field winding. The armature winding is on the stator and the field winding is on the rotor. For a three phase generator‚ the windings of each phase of the armature are displaces by 120 degrees from each other around the inside periphery

Newton’s first law (the Law of inertia) states that “when an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force”. What this law actually means is that an object (whether it’s moving

Tesla will most likely face some degree of cultural inertia. The culture of‚ say‚ Germany or China may not mesh particularly well with the one that intrigued Californians. Germany‚ with its penchant for efficient‚ powerful technology and a slew of luxury car juggernauts‚ may easily be less impressed with Tesla’s

As people go on in the coaster you will experience many forces‚ when on earth gravity is pushing down on you and on the roller coaster the same is applied. The bodies force of inertia that you feel a force in front of you. Acceleration is measured in G-force. The air you experience on the roller coaster is due to that your body is not completely solid.
