- Photographs at a scale of S are required to cover an area X-mi square. The camera has a focal length f and focal plane dimensions of 9 x 9 in. If endlap is 60% and sidelap 30%, how many photos will be required to cover the area for the data given below? S=1:6300; X = 6; f = 152.4 mm Express your answer as an integer. Number of photos = 17 ΑΣΦ ↓↑ vecThe atmosphere is the common unit for measuring atmospheric pressure by metorologists. Select one True FalseShowing the figure as shown in figure 2 determine the following A) Location of Neutral Axis from the bottom • B) Moment of inertia along x-axis (lx) 30 mm 40 mm 30 mm r = 100 mm hollow r=20 70 mm
- 28.30mm 28.20mm 90MPa 6-A 20mm by 20mm square is etched onto a metal bar prior to loading. Upon loading, the dimensions of the etched shape become those indicated on the figure. Determine Young's modulus E and Poisson's ratio of the bar material.1. In the figure shown: a) Determine the centroidal distance (ỹ) from the X-Axis b) Determine the moment of inertia at the neutral axis. A 75 mm 100 mm A A B BA steel tape of nominal length 200 m with a plumb bob of mass 16 kg attached to it was used to measure a length down a shaft as 160.852 m. The mean temperature during the measurement was 4 C. If the tape was standardized to be 200.0014m under a tension of 115 N at 20" C temperature, determine the correct measured length. The following data may be used: Mass of tape = 0.07 kg/m Cross-sectional area of tape= 10 mm Coefficient of linear expansion a = 11x 10/°C Modulus of clasticity = 2x 10° Nmm Acceleration due to gravity 9.807 m's.
- :Pick up the incorrect statement from the following The straight distance between end points of a suspended tape is reduced by an amount called the sag correction While measuring a distance with a tape of length 100.005 m, the distance to be increasing by 0.005 m for each tape length A 100 m tape of cross section 10 mm x 0.25 mm stretches about 10 mm under 5 kg pull An increase in temperature causes a tape to increase in length and the measured distance is too largeSteve Roger measured a line and found it out to be 950 m long using a 20 – m tape under a steady pull of 4 kg at a mean temperature of 25°C. The tape was held in the air and supported at both ends and at the center. Determine the correct length of the line if the tape used is of standard length at 22°C under a pull of 6 kg. Assume the cross-sectional area of tape to be 0.05 cm2, modulus of elasticity as 2.10 x 10^6 kg/cm^2, weighs 0.08 kg/m, and a Coefficient of Thermal Expansion to be 0.0000116/°C.1.
