Suppose you have $8,000 in savings when the price level index is at 100.
Instructions: Enter your responses rounded to the nearest whole number.
(a) If inflation pushes the price level up by 10 percent, what will be the real value of your savings?
(b) What is the real value of your savings if the price level declines by 10 percent?
a component in a packaging machine is subjected to a tensile load of 36.6 KN which will be repeated several times over the life of the machine. The cross-section of the component is 12 mm thick and 20 mm wide.
A concrete box girder bridge has the rectangular x-section. The box is prismatic and considered thin-walled. It span is L=48m and simply supported at points A,B,C and D. The supports are assume to be able to transfer tensile forces.
Determine the magnitude of the average force acting on a highway bumper when a 5000-lb car traveling at 60 mph crashes against it. The time interval during which the car is brought to rest is 0.3 s.
A sailor is being rescued using a boatswain's chair that issuspended from a pulley that can roll freely on the support cableACB amd is pulled at a constant speed by cablle CD
Member ABC is supported by cable CD and a square collar at A that fits loosely over the smooth square rod. Determine the tension in cable CD. The smooth rod is fixed at its base and cannot rotate.
Produce a plan drawing showing the position of each borehole (coordinates are given with the borehole logs) and from your plan drawing, justify the best position for a cross section to be placed.
Write a computer program that for a given state of plane stress and a given yield strength of a ductile material, can be used to determine whether the material will yield.
The relative density of a sloped sand deposit is known to be 75%. Water is observed to be seeped through this slope at a rate such that the discharge velocity is 0.6 m/day. If the hydraulic conductivity for this deposit is 4×10-4 m/s.
Compute the electrical conductivity of a 7.4-mm diameter cylindrical semiconductor specimen 28 mm long in which a current of 0.20 A passes in an axial direction.
Three parallel line loads of 500kN/m are applied at ground level in a straight line 4.0m apart. Determine the increase in vertical stress at 2.0m below ground level beneath the middle load.
Due to temperature change, a 1/32" hole mismatching occurred. What is the pulling force, in lbs, to be applied for one of the plates to match the two holes The plate length is 3 ft (from the left end to the hole) and its cross section is 1/8" x 1"..
