many hours did the carpenter work on the job? 6. What is the area of a rectangular floor that is 7'-3" long and 4'-2" wide? 7. There are 15 risers in a set of stairs running from the basement to the first floor. Each riser is 7 1/4" high. What is the distance between floors? 8. The distance between two floors is 9'-0 1/2". If 14 risers are to be used in a set of stairs, what is the height of each riser?

Gentlemen, please help to solve a,b,c as I faced confusing questions about screw jack. Conditions are: screw jack is lifting 3.2 tonnes, screw pitch is 12 mm, diameter of the screw is 5 mm. Coefficient of friction was not given but I think we will need it for total force calculation, lets take it 0.2. a) Calculate horizontal component to move the load - what is ment here by horizontal component? b) Calculate vertical component to move the load - what is ment here by vertical component? c) Total force needed to move the load with a lever of 0.82m d) Velocity ratio (VR=distance by effort/distance by load)       Distance by effort (lever)=2 x 3.14 x 0.82 = 5.15m       Distance by load = pitch= 12mm= 0.012 m        VR=5.15/0.012= approx 429. e) Calculate efficiency. For this we need to have MA       (mechanical advantage). It can be calculated when we know total force.          Efficiency=Load (3200 x 9.8) / effort

Determine the required mass of block A so that when it is released from rest, it moves the 5 kg block B a distance of 0.75 m up along the smooth inclined plane in t = 2 seconds. Neglect the mass of the pulleys and cords. %3D

In a shaper machine, the crank rotates at constant speed of 130 r.p.m. The angle travelled by the crank during cutting stroke is 267.2o and during return stroke is 92.8o. Compute and identify the nearest value of ratio of the time of cutting stroke to the return stroke. a. 1.71 b. 2.88 c. 0.347 d. 174.4

thank you can u plz solve f&g now

Use the formulas for the hydraulic press to find the value. A force of 30 lb is applied to a piston of radius 5 in. of a hydraulic press. The large piston has a radius of 25 in. What force (in pounds) is exerted by the large piston?
