Write a shell script called Grading.sh that will accept StudentID and Grade and the student are graded using the following grading criteria: 80 and above, Destination, 79-60, Merit, 59 -50, Pass, 49-40, Supplement and 39 and below, Fail. The program should add the records to a file called StudentGrades.txt.

It is required to lift a load of 1.2 tons through a height of 320
mm by using a screw jack under the following condition:
• The available material of the screw is plain carbon steel
which has elastic strength in tension and compression of
200 MPa and in shear 120 MPa respectively.
• The available material of the nut is phosphor-bronze for
which the elastic limit may be taken as 100 MPa in
tension, 90 MPa in compression and 80 MPa in shear.
• The bearing pressure between the nut and the screw is
not to exceed 20 N/mm?.
Design and draw the screw jack. The design should include
the design of:
1) The screw,
2) Nut,
3) Handle and Cup, and
4) Body.
Draw to full scale an isometric and multi-views for the screw
jack.
The design report should include the following:
• Calculation sheet.
• Detail drawing (soft).
• References including material data sheets and used
curves and tables.
• Assume any missing data.

A 70kg box is slid along a horizontal floor by a horizontal 400Nt force. Find the distance travelled by the box in 5 seconds if
a) there is no friction
b) coefficient of friction = 0.20
In 100 mL of 6.02 M HCl, which has a gravity of 1.10 g/ml, a strip of magnesium metal with a mass of 1.22 g dissolves. The initial temperature of the hydrochloric acid is 23.0 °C, and the end temperature of the solution is 45.5 °C. Calculate AH for the reaction under the conditions of the experiment. (The heat capacity of the calorimeter is 562 J/°C, specific heat of the finals is 4.184 /gºC.) the reaction is: Mg(s) + HCl(aq) → MgCl2(aq) + H2(g)
