11. 3.7 Uneven Legs 3.7a. A 40 kg table that is 3 m long is supported by two legs positioned as shown. The legs are made of aluminum, with diameters 10 cm (left leg) and 5 cm (right leg). 1 m 2 m What is the compressive stress on the left leg in N/mº? Enter answer here I 12. 3.7b. What is the compressive stress on the right leg in N/mº? Enter answer here 14.3.74 if the legs are I m long and the Young's modulus of aluminum is 70 GP, at what small angle does the table sit in poder? I point Enter answer here I

The questions below refer to the diagram. Protein X is a putative regulator of cell polarity. Muun Epithelium Protein X فاقات Microfilaments Microtubules Nucleus ER Protein X EMT MET Protein X a. What does EMT and MET refer to in this diagram? Are these usually reversible states? What transition in cell polarity states does it involve? What processes are EMT and MET involved in during the lifespan of a human? (4 marks) b. During the EMT process, for a cell to migrate through a tissue, what must it do to the ECM? What enzymes are used to achieve this? (2 marks) c. Could Protein X be E-Cadherin? Explain your reasoning. (2 marks) d. If Protein X was a member of the Scribble complex, would its role be upstream or downstream from integrin signalling in directed migration? What would you expect the effect of the loss of function of Protein X be on microtubule organisation during directed migration? (2 marks)

8.6 (a) Assume the inverters have a delay of 1 ns and the other gates have a delay of 2 ns. Initially A = B = C = 0 and D = 1;C changes to 1 at time 2 ns. Draw a timing dia- gram showing the glitch corresponding to the hazard. (b) Modify the circuit so that it is hazard free. (Leave the circuit as a two-level, OR-AND circuit.) D Et H B

A soap film(n = 1.33) in air is 320 nm thick. If it is illuminated with white light at normal incidence, what colour will it appear to be in reflected light? A soap film(n = 1.33) in air is 320 nm thick. If it is illuminated with white light at normal incidence, what colour will it appear to be in reflected light?

​​​​​​​ EXERCISE - INDIVIDUAL: Convert from big- to little-endian in MIPS n the files for this lab, you have been given mips_networking.s, a MIPS assembler program that reads one number and chen prints it. Add code to mips_networking.s to make it equivalent to this C program: // Reads a 4-byte value and reverses the byte order, then prints it \#define BYTE_MASK QxFF int main(void) \{ int32_t network_bytes; scanf("\%d", \&network_bytes); int32_t computer_bytes \( =0 \); uint32_t byte_mask = BYTE_MASK; computer_bytes \( \mid= \) (network_bytes \& byte_mask) \( \ll 24 \); computer_bytes \( \mid= \) (network_bytes \& (byte_mask \( \ll 8 \) ) ) \( \ll 8 \); computer_bytes \( \mid= \) (network_bytes \& (byte_mask \( \langle<16)) \gg> \); computer_bytes \( \mid= \) (network_bytes \& (byte_mask \( \langle\langle 24) \) ) \( >>24 \); printf("\%d", computer_bytes); return 0 ; \} n other words, it should read one number, network_bytes, reverse the byte order inside it, and print the result. The MIPS documentation guide provides a set of bitwise operations that will be useful for this.
