A civil engineer used a 200 m tape in measuring an inclined distance. The measured length on the slope was recorded to be 459.20 m long. The difference in elevation between the initial point and the end point was found to be 1.25 m. The 30 m tape is of standard length at a temperature of 10 degrees Celsius and a pull of 50 kg. During measurement the temperature reading was 15 degrees Celsius and the tape was supported at both ends with an applied pull of 75 kg. The cross-sectional area of the tape is 6.50 mm^2, and the modulus of elasticity is 200,000 kg/mm^2. The tape has a mass of 0.075 kg/m. Take C = 0.0000116 per degrees Celsius. b) Determine the Correction due to Pull for the measured line

Khufra works at a spring factory and he was assigned to test a certain spring, whose constant is 50 N/m, attached to a 50-kg block in an incline (8=30°). With the spring initially at equilibrium position, the block was pulled 0.3 meters down the incline by a 50-N external force applied parallel to the path. If the coefficient of kinetic friction is 0.3, determine the: a) normal force (in Newtons) b) work done by the spring (in Joules) www
