Which of the following statements is correct in regards to battery reserve capacity?
A. This rating indicates the number of minutes a new fully charge battery at 80° F (26.6° C ) can sustain a load of 25 amperes before the battery voltage draw at 1.75 volts per cell or 10.5volts for a 12 volt battery.
B. This rating indicates the number of minutes a new fully charge battery at 70° F (21.1° C ) can sustain a load of 25 amperes before the battery voltage draw at 2.0 volts per cell or 12.2 volts for a 12 volt battery.
C. Indicates how long a battery can provide enough power to keep the ignition, head and tail lights, windshield wipers, and heater operating if the battery is fully charged.

Computer investigation of wind load on a building frame.
Case 1: The columns and girders of the rigid building frame in Figure P5.58 have been
designed initially for vertical load as specified by the building code. Floor beams are
connected to columns by rigid joints. As part of the design, the building frame must be
checked for lateral deflection under the 0.8 kip/ft wind load to ensure that lateral displacement
will not damage the exterior walls attached to the structural frame. If the code requires that
the maximum lateral deflection at the top of the roof not exceed 0.48 in. to prevent damage to
the exterior walls, is the building frame sufficiently stiff to satisfy this requirement?
Case 2: If the bases of the columns at point A and F are attached to the foundations by fixed
supports instead of pin supports, how much is the lateral deflection at joint D reduced?
Case 3: If a pin-connected diagonal bar bracing with a 2 in. × 2 in. square cross section
running from support A to joint E is added, determine the lateral deflection at joint D. Assume
pin supports at joints A and F.
For the columns, I = 640 in. 4 and A = 17.9 in.2; for the girders, I = 800 in. 4 and A = 11.8 in. 2 ;
for the diagonal brace, A = 4 in. 2 . Use E = 29,000 ksi.
